expansive,cataclastic and low strength along the Nanning-Kudring Railway in Baize Basin of the GuangxiProvince, and analyses the harm of these characteristics to the cut slope engineering and therule of deformation of the cut slope of the expansive rock.

Real-time simulation for slope engineering of highway;

The slaking property and its effect on the topsoil slip of swelling rock cut slope;

According to the problem of failure and instability in roadbed and cutting engineering of underground karst cavity,on the basis of inhomogeneous elastic damage model,this thesis propose the FEM back-analysis from instability-strength degradation,to describe inhomogeneity of material suppose that the material parameter obeys statistical distribution.

Observation and analysis of cutting slope settlement in permafrost region;

Simulation analysis of elastoplastic FEM for stability of bedding rock cutting slope;

Analysis of cutting slope reinforcement in swelling rock and soil;

Design and application of a monitoring system for unstable cut slope;

Analysis and treatment on deformation mechanism of bedding-slip cut slope;

In order to study the effects of natural restoration of vegetation of highway rocky cut slope,and provide references for the protection design of highway slope and design of vegetation restoration on mountainous area,6 provincial highways and 2 national highways are investigated in the middle of Shandong Province.
