| Abstract: | Through comprehensive study on a large amount of engineering examples,the primary failure causes of Guangdong expressway cut slopes in recent years,the concept of landslip prevention designing,slope treatment program,slope monitoring and slope emergency treatment measures are investigated. The investigation revealed that the instabilities of cut slopes are due to the adverse conditions in water and climate,strata,lithology,geology structure, human activities or engineering activities,etc..Therefore,a five-stage dynamic designing method is put forward,which consists of geologic mapping,engineering geological investigation,comprehensive analyses of slope stability,schematic designing,and detailed construction drawing designing.Finally,an actual case of slope stabilization is used to illustrate the dynamic designing method. |
