Abstract
The high fill subgrade center in the Dapingpo section of the freeway that from Qingzhen to Zhenning reach more than 30 metres highly,the hidden trouble of the basis has three: the karst crevasse,the high liquid limit clay,the small limestone cave.Through dynamic compaction construction on the subgrade,sped up the ground solidifying speed,reduced the ground solidifying time,this subgrade processing means effectively controlled the settlement of the subgrade,guaranteed the subgrade stability by settlement observation of the subgrade.
