Soil-Structure Interaction - Planning Phase 2 LHPOST Site Visit

This ongoing research will help answer the questions that continue to arise as Reclamation is faced with detailed analysis and modifications of spillways and other earth retaining structures subjected to significant seismic loading. The objective of this research is a better analytical tool to predict the seismic lateral earth pressures for configurations that include groundwater, cohesion and compaction/in-place density effects under various ground accelerations. This report represents the completion of the first year of the second phase (Planning Phase 2) of this research project. The ultimate project purpose completing a full scale shake table test of a concrete cantilever retaining wall.
