The Collapse Incident Analysis and Control Techniques on Slope in Xiangtan City

Through the symptotic homogenization method,make geogrid-reinforced roadbed equivalent to the material with a single elastic parameters.Using Ansys to establish geogrid-reinforced roadbed of three dimension finite element model.Use mobile constant load simulate traffic load,when role traffic load research the dynamic response of geogrid-reinforced roadbed.Research the schedule curve change rule of different points Mises equivalent stress,vertical displacement,vertical acceleration,and with the single round wheel load value,driving speed,depth from the roadbed surface change,the law change of dynamic response.
