Safety analysis of high engineering slopes along the west approach road of ZheGu mountain tunnel

摘要

The long-term safety of highway slopes in mountain areas with complex geological conditionshas a direct relation not only to the safe operation of the highway itself,but also to the life and wealth security ofthe people who live along it. In this paper some typical high slopes along the west approach road of the ZheGumountain tunnel,the long-term safety of the slopes were systematically studied through the in-situ trackinginvestigation,the deformation monitoring of slopes and stress of anchors,the FEM numerical simulation ofinteraction between slope body and anchoring structure,and the fuzzy comprehensive assessment method. As aresult,,these slopes were classified in terms of safety.
