Mr. Jeremy Kosegi is currently an Engineering project Manager at the Citizens Energy Group. He got his B.S. in Civil Engineering from Purdue University and later a Masters in Environmental Engineering from University of Illinois Urbana-Champagin.
The DigIndy Project is a nearly 28-mile long network of 18 foot diameter deep rock tunnels being built 250-feet beneath the city. Beginning near the Indiana State Fairgrounds on the north, and ending on the south side of Indianapolis, DigIndy will be the largest public works project in the city’s history.
Tunnel system will extend along Fall Creek, White River, Pogues Run, Pleasant Run and Bean Creek to create a collective, underground storage and transport facility for wastewater (sewage). All sewage stored and transported in the tunnel system is sewage that otherwise could have gone directly into our waterways. The tunnel system is a component of the federally-mandated plan to reduce raw sewage overflows into our waterways.

Izzat Idriss, PhD
Professor Emeritus – University of California Davis
Starting in the early 1970s, examination of recorded data at soil and rock sites over the past years has indicated that: earthquake ground motions recorded at “rock” sites are greater than those recorded at soil sites at distances close to the source; and the earthquake ground motions recorded at “rock” sites are smaller than those recorded at soil sites at distances farther from the source. The study by Duke et al. (1972) relied mostly on recordings from the 1971 San Fernando earthquake. The study by Seed et al. (1976) included a number of other earthquakes in addition to the 1971 San Fernando earthquake.
The 2014 NGA West2 studies included collection of numerous earthquake ground motion data recorded at a wide range of site conditions. These indicate similar trends to those obtained in the 1970s. This difference in the variations of earthquake ground motions recorded on “rock” sites compared to those recorded on soil sites is attributable to the nonlinear site effects. The current 2014 NGA West2 published models are also examined to assess whether the trends exhibited are captured by the attenuation relationships employed in these models. The results of this examination will be presented during this talk. Essentially, none of the 2014 NGA West2 relationships captures the trend sufficiently to fully capture the nonlinear site effects evident in the data.
I.M. Idriss is a UC Davis professor emeritus of geotechnical engineering whose research on soil mechanics and foundation engineering has influenced the construction of dams, nuclear power plants, seaports, office buildings, residences, hospitals, railways, and bridges around the world.

David R. Groholski, PhD, PE
Senior Engineer, Civil Engineering
Ka Loko Dam, in Kauai, Hawaii, failed suddenly and catastrophically on March 14, 2006. The resulting broad “U”-shaped breach was marked by three distinct topographic benches. The lowest bench was founded on a greasy, waxy, gel-like material produced by in-place weathering of late-stage volcanic materials. Gravel-size pieces in the hydraulic fill of the embankment derived from these materials were also weathered in place. Engineers and geologists generally assume that the strength, stiffness, and durability of bedrock, earth, and embankment materials will not vary over the operating life of a hydraulic fill dam. However, bedrock materials can progressively weather into soil constituents over “geologic time.” In the case of Ka Loko, late-stage volcanic materials substantially weathered in-place over approximately 115 years. Prolonged exposure to seepage of anoxic water completely weathered the bedrock to saprolite, including weak, sensitive, fine, spherical halloysite clay.

High plasticity deltaic estuarine clays (non-liquefiable NEHRP F sites) are the predominant soils in Guayaquil City in Ecuador. A new geotechnical characterization scheme for these soils was proposed based on geological studies, historical data of geotechnical and insitu explorations. Accordingly, some correlations were developed between geotechnical parameters and seismic response properties to characterize the Guayaquil soil deposits for dynamic analyses. Based on the calculated elastic and inelastic responses of these soils, a seismic zonation for the city was proposed. In addition, a detailed procedure for estimating a design site response spectrum for Guayaquil City’s prevalent soil conditions was developed. The experimental results and numerical procedures presented in this research provide a framework for understanding the mechanical behavior of the estuarine-deltaic, high plasticity, diatomaceous, naturally cemented clay and provide key information for the design of engineered systems in Guayaquil and for cities worldwide, with similar geomorphological, seismic, and geotechnical characteristics.

Camilo Marulanda, Ph.D.
Technical Manager, INGETEC
This presentation presents a brief summary of the origin of metamorphic rocks, specially schist and the presence of shear or gouge zones in metamorphic rocks, as defects that induce weakness characteristics to the rock mass and that depart substantially from the traditionally evaluation of joints and discontinuities, turning eventually into failure surfaces that govern the stability conditions of surface works. The effect these weak zones inflict into the metamorphic rock mass, especially to schist, causing significant slope stability problems, is illustrated through three case histories. The presence of such defects in the rock mass, detected and analyzed by means of exploratory holes drilled from the surface, can be hardly anticipated during the design stage as far as location, dip direction and geotechnical characteristics, given their erratic alignment within the rock mass, and their disguise during the drilling processes when the clay infill is washed away by the drill water, making their recognition and readiness for lab test sampling even more difficult. Special care of these geologic features, often present in metamorphic rocks, must be taken through: 1) direct exploration –such as galleries–, 2) the elaboration and interpretation of adequate geological models and corresponding sensitivity analyses of shear strength parameters of the established failure surfaces and 3) sound decision making and implementation of stabilization measures based on engineering judgment.

Jian Chu, Ph.D.
Nanyang Technological University, Singapore
Static liquefaction or flowslide is considered as one of the most common failure mechanisms for granular slopes or tailings dams. One of design approaches adopted is to use the residual strength or the so-called post-liquefaction undrained shear strength. However, there are a number of problems associated with this approach. One of them is that the post-liquefaction strength cannot be determined properly experimentally. The assumption of an undrained condition is also questionable for sand or tailings with relatively high permeability under static loading conditions. In this seminar, instability behavior of sand under undrained, drained, and other than undrained conditions are presented to illustrate that instability does not have to occur under an undrained condition and “undrained” does not have to be taken as a design assumption. Based on the new findings, a different design approach to use the stress ratio of instability line or the peak strength ratio is suggested.

Australia and New Zealand contain many unusual and/or problematic soils. Failure tounderstand the properties and behavior of these materials will lead to major cost overrunsand substantial difficulties in projects involving these materials. Conversely, designingthe projects to take into account the unusual properties can lead to significant costsavings. A number of case histories from both countries will be presented to illustrate theunique properties and how these properties can either lead to an economical design or toproblems. In New Zealand, there are two groups of soils that lead to fairly unusualproblems. The first is the pumiceous materials of the Central Volcanic Zone and theirallophane rich weathered materials, and the second are the residual soils of Auckland andNorthland. All of these materials have high void ratios, but contrary to expectation, theyare often quite strong and stiff. Once a critical yield stress (or strain) is reached however,their behavior changes quite radically. The reasons and consequences will be discussed.
