ANALYSIS OF INCREMENTAL EXCAVATION BASED ON CRITICAL STATE THEORY

In this paper, the recently developed excavation analysis algorithm proposed by Borja et al (1989) is applied to a more reaistic constitutive model in geomechanics, thus broadening the technique's practical application. In the context of finite element analysis based on displacement formulation, this algorithm provides a theoretically correct and analytically efficient solution to the basic problem of nonlinear elastoplastic modeling of incremental excavation. This is a description of an accurate, stable, and efficient algorithm for analyzing the problem of nonlinear incremental excavation employing critical-state theory. It is used to predict the deformation behavior of braced excavations in a young bay mud deposit near San Francisco Bay.
