A Predictive Modeling Approach For Assessing Seismic Soil Liquefaction Potential Using Cpt Data, Jonathan Paul Schmidt
A Predictive Modeling Approach For Assessing Seismic Soil Liquefaction Potential Using Cpt Data, Jonathan Paul Schmidt
Master's Theses
Soil liquefaction, or loss of strength due to excess pore water pressures generated during dynamic loading, is a main cause of damage during earthquakes. When a soil liquefies (referred to as triggering), it may lose its ability to support overlying structures, deform vertically or laterally, or cause buoyant uplift of buried utilities. Empirical liquefaction models, used to predict liquefaction potential based upon in-situ soil index property measurements and anticipated level of seismic loading, are the standard of practice for assessing liquefaction triggering. However, many current models do not incorporate predictor variable uncertainty or do so in a limited fashion. Additionally, …

Case Study: Using Geofoam On A School Project In Encinitas, Ca, Matthew D. Gaebe
Construction Management
This paper is a case study that identifies why Geofoam was used as in-fill material for a construction project located at a high school in Encinitas, CA. The Geofoam was installed under a stairway that connects to a structural retaining wall. The concrete formwork was connected directly to the foam and the stairs were poured in place onsite. The foam acted as the on-grade material, so the concrete stairs did not have to be self-supporting. The purpose of this study is to understand the benefits of using Geofoam, as the in-fill material, as opposed to other traditional materials. An analysis …
