The illogical design of intercepting drain on the top of highway slope has much influence on the stability of highway slope,which is an importance reason causing highway slope disasters.

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.

Treatment of Road Cutting Slope and Reliabilty Analysis on Slope Stability;

Based on the experience of construction,this paper introduces the design,construction and quality assessment of the appli- cation of hewed blast in the road cutting slope and provides some practical technical parameter about the hewed blast.

On the basis of field investigation,the method of fuzzy synthetic evaluation is used to study the stability of a road cutting slope in Sichuan in this paper and the method is proved to be effective.
