摘要

A cost-and time-effective derivation of the strength parameters for deep-seated sliding surfaces in natural slopes consisting of highly weathered or fractured rocks is of high practical importance. A force-equilibrium-based finite displacement method (FFDM) is used to back-calculate material property to alleviate possible difficulties in evaluating strength and deformation properties of highly weathered rocks using undisturbed soil sampling for a deep-seated sliding surface. The FFDM incorporates Bishop's slice method and nonlinear shear stress-displacement relationships. As a result, shear displacements along a circular potential failure surface can be computed. The displacement-related parameters obtained from a back-analysis using FFDM are then used to predict long-term cumulative slope displacements induced by periodic ground water table fluctuations. Results of the analytical study show that the long-term cumulative slope displacement of the slope can be well-predicted using the displacement-related parameters back-calculated from the first event of slope displacement induced by a groundwater table rise.
