Subgrade Settlement Stability And Road Slow Shop Technology

The road surface slow laying technology plan is in the mountainous area highway construction, nimble utilization "preventive maintenance" the viewpoint proposed a feasible technical plan, its merit is tends to stable process period in the roadbed subsidence does not affect the operation of the highway, enable this path to have the best economical rationality.In the road surface slow laying technology plan implementation process, needs to the roadbed subsidence stable analysis fair price. This article broad high speed as depends on the project take the wadding, has conducted the research to the roadbed subsidence stability analysis method, has used the restraining analysis method and the utilization catastrophe theory analysis soil body stability analysis method separately. The former direct-viewing, simple, feasible, the latter has the deep mathematics foundation, very is also easy using the Excel tool to carry on the data processing. Two methods obtain result basic consistent, may carry on the confirmation mutually.
