摘要

Slope stability analysis is an important research field of geotechnical engineering. It has been continuously developed in recent decades. A variety of analysis methods have been applied, among which the unbalanced thrust method is widely used in a large number of geological engineering cases. In slope stability analysis, the calculation of critical sliding field can not only easily and accurately approximate the critical sliding surface of arbitrary shape, but also display all other dangerous sliding surfaces at the same time. The degree of stability is expressed by residual thrust. Based on the theory of global critical sliding field of slope, this paper realizes the search of local critical sliding surface with arbitrary shape. The calculation and analysis show that the calculation result of the software is accurate, stable and easy to operate. It is widely used in practical slope geological engineering.
