Earthquake Resistance of Earth and Rock-Fill Dams. Report 4. Transient Two-Dimensional Analysis of Soils by Latticework Method, Lopez Dam Case Study.
Abstract
The background development is presented for a two-dimensional shear stress analysis procedure that solves the dynamic equations in a latticework of line elements, and examples are given. The material deformation relation used in the procedure may be any law that can be used in a one-dimensional characteristics method analysis, e.g., linear, viscoelastic, or non-linear hysteretic. Also, irregular and interactive boundary conditions may be handled. Input motions in both the horizontal and vertical directions are handled, and may be transient and phase varying. Initial stresses are accounted for in the analysis. The response of Lopez Dam to the 1971 San Fernando Earthquake is studied using one-dimensional, one-dimensional wedge-shear-slice, and two-dimensional analyses and non-linear material properties.
