Abstract

Abstract

The resistance from soft soil layers is smaller while piling in soft foundation.The stress wave will propagate along pile body when the pile head is stricken by hammer with a certain velocity.And it will turn into tensile waves when reflected at the bottom of pile.Thus,one tensile stress region on pile body will appear near pile bottom because of intervention between the incident waves and the reflect waves,which can cause pile to be fractured or spalled.Based on one dimensional wave theory,the primary discussion on this phenomenon is done with finite difference method,and some benefit conclusions and suggestions are obtained.In a way,they have definite reference value for engineers.
