Study on the Force Characteristics of Rubble Pile Composite Foundation in Sand-filled Foundation
摘要
Abstract
For the sand-filled foundation in Donghai Island,Zhanjiang City,Guangdong Province,static load test and pile-soil stress test were carried out to study the average inter-pile soil stress,pile top stress,pile-soil stress ratio,and load-sharing ratio change rule of the rubble pile composite foundation under graded loading.The results show that:the pile-soil stress ratio of rubble pile composite foundation in sand-filled foundation is between 1.0 and 2.0;the load share borne by the soil between piles is about 80.0％-90.0％,and the load share borne by rubble piles is about 10.0％-20.0％;the bearing capacity of the foundation between piles can be increased by 51.6％after rubble pile composite foundation treatment compared with that before treatment.关键词
