The Influence of Construction Step Sequence and Nonlinear Material Behavior on Cracking of Earth and Rock-Fill Dams.

摘要

The WES-Palmerton finite element computer program was used to make a preliminary study of the effects of construction sequence and nonlinear modulus on cracking in earth dams. Results of the nonlinear analysis are compared with linear elastic one-step analyses and linear elastic construction step analyses including low tension modulus. Linear elastic,one-step analyses gave the largest tension zone,and no tension zone occurred in the nonlinear analyses. No provisions were included for tensile strength of the soil.
