Investigation of the sequential excavation of a soil-rock-mixture slope using the numerical manifold method
TL;DR: In this paper, two modifications are made to the numerical manifold method (NMM) to investigate the stability of a soil-rock-mixture (SRM) slope subjected to sequential excavation.

FDEM-flow3D: A 3D hydro-mechanical coupled model considering the pore seepage of rock matrix for simulating three-dimensional hydraulic fracturing
Chengzeng Yan,Hong Zheng +1 more
TL;DR: In this paper, a coupled model that simultaneously considers the pore seepage of a rock matrix and the fracture seepages is proposed to simulate three-dimensional hydraulic fracturing, which appropriately takes into account the fluid leak-off into the surrounding rock matrix from the fracture.

On two definitions of the factor of safety commonly used in the finite element slope stability analysis
TL;DR: In this article, a uniform initial value problem of ordinary differential equations for locating the critical slip lines corresponding to the two commonly used definitions was formulated and a prediction-correction procedure was proposed.

Modeling the entire progressive failure process of rock slopes using a strength-based criterion
TL;DR: In this article, a series of techniques are incorporated into the original NMM (numerical manifold method) to simulate the entire process of the progressive failure of rock slopes, including strength-based LT criterion, which can account for tensile cracks, tensile shear cracks and compressive-shear cracks.

A coupled thermo-mechanical model based on the combined finite-discrete element method for simulating thermal cracking of rock
Chengzeng Yan,Hong Zheng +1 more
TL;DR: In this article, a coupled thermo-mechanical model (termed FDEM-TM) is proposed to simulate thermal cracking of rock, which is based on a combined finite-discrete element method (FDEM).
