Unlined Length Effect on the Tunnel Face Stability and Collapse Mechanisms in c-ϕ Soils
A Numerical Study with Advanced Mesh Adaptive Strategies
This paper presents a stability study on the collapse mechanisms of a plane-strain tunnel face in c-ϕ soils using the upper bound finite element method with rigid translatory moving elements (UBFELA-RTME) and nonlinear programming technique. Practical considerations are given ...
Material point method simulation of hydro-mechanical behaviour in two-phase porous geomaterials
A state-of-the-art review
The material point method (MPM) has been gaining increasing popularity as an appropriate approach to the solution of coupled hydro-mechanical problems involving large deformation. In this paper, we survey the current state-of-the-art in the MPM simulation of hydro-mechanical b ...
The stability and collapse mechanism of tunnel faces are simplified conservatively to two-dimensional plane strain models along the longitudinal middle line of tunnel. Using the upper bound finite element method with rigid translatory moving element (UBFEM-RTME), a series of s ...
