The pressure wave equations of impounded water and pore water are solved with the dynamic response of sediment solids and the vibration of the dam. The sediment is modeled as a poroelastic medium. The effects of sediment thickness, material properties, and the compressibility of pore water will be analyzed. Inc. The project constitutes the first phase of a two-year study. The objective is to develop a tool for conducting coupled analysis of soils under seismic excitation.
Work includes a review of the current research on effective stress analysis.
Based upon this review of different methods, a proper consitutive law will be adopted for further development. The final objective is to combine this effort with finite element or finite difference methods to quantify soil responses for use in seismic resistance design. It prepared technology status and evaluation reports on innovative technologies and sponsors an annual conference on technology applications and assessment. This project will develop a training program together with associated materials on Intermodal Transport Coordination for PennDOT personnel. The overall goal is to gain fundamental understanding of the chemistry and physics involved in mercury adsorption.
