Dynamic Optimal Design And Integrated Control System Of Cut Slope On High-type Highway

With the rapid development of the classified highway constructions,the consolidation and protection of highway side slope are dayly important,especially cut slope,it greatly influences to traffic and people's life and property,at the same time to aroud conditions,water and soil flowage and ecological protection,but there are without a ripe or reasonable rule about highway side slope design and protection in our country,so it is critical to set up a synthetic prevention system of highway cut slope.In this paper ,connectly discussed and studied were the design and actual protection of classified highway cut slope based on the joint research project,Research on Actual Protection of Classified Highway Cut Slope.The paper first analyzed and syntheticed the corresponding results in design and protection of classified highway cut slope ,discussed a great many ways about stability analysis calculate and prevention,it provided basis for the cut slope integrated prevention system.By tests and reasearches on mechanical parameters of soil and soil-rocky side slopes,the paper provided numerical model,the relation of resisting cutting strength and water content or dry unit weight,stability factor or grade of side slope.The paper get the most dange slip plane by analytical method to check the stability of verious slope.Also the paper proposed dynamic optimal design to highway cut slope as intellgent expert system of protection engineering CAD.It shoud be paied attention to environmental conservation, plant, culture and so on, therefore integrated prevention system of highway cut slope with Ecological landscape highway should be adopted,and the recommend plan of Hunan was proposed too. According to the reasearches, good effect was received on the new high-type highway cut slope in chenzhou Guiyang-Jiahe.
