Sequential excavation analysis of soil-rock-mixture slopes using an improved numerical manifold method with multiple layers of mathematical cover systems

An improved numerical manifold method (INMM) with multiple layers of mathematical cover (MC) systems is employed for a sequential excavation analysis of SRM (soil-rock-mixture) slopes. For the purpose of obtaining the FOS (factor of safety) of a SRM slope, an enhanced SSRT (shear strength reduction technique) is used in the INMM. Furthermore, two algorithms, i.e., an algorithm to identify the excavated MEs (manifold elements) and an algorithm to...
