Abstract
Bridge pile foundation is an important part of the bridge,and its quality directly affects the engineering quality of the entire bridge.The inclusion of mud in bridge pile foundation has always been a major and difficult problem in bridge engineering.This paper first analyzes the causes of bridge pile foundation mud entrapment based on two common pile foundation hole-forming processes:rotary drilling and percussion drilling.Based on site conditions and defect locations,it summarizes the common treatment measures for bridge pile foundation mud entrapment.Three on-site inspection methods are elaborated considering the inspection regulations and frequency.Then,the effects before and after the treatment of pile foundation mud entrapment are compared based on actual engineering cases.Finally,the application scope of the three treatment measures is discussed,which provides a certain guidance for bridge pile foundation construction.关键词
