Abstract:Tensile cracks in soil slopes, especially developing at the crown, have been increasingly recognized as the signal of slope metastability. In this paper, the role of crown cracks in natural soil slopes was investigated and their effect on stability was studied. A numerical slope model based on the extended finite element method (XFEM) simulating the tensile behavior of soil was used. Before the simulation, a numerical soil tensile test was applied to validate the use of XFEM on tensile behavior of soil. Slope … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
