摘要
根据基底下埋设土压力盒的观测结果,研究了墩-筏基础的工作机理;明确了基底压力及分布;分析了墩与筏基的荷载分配比.应用该项成果已成功地设计了另一幢14层建筑的基础,并获得了较好的经济效益.
This paper investigates the performance of a pier-raft foundation in situ. The contact pressure and its distribution, the load sharing between piers and the raft are monitored by the installed earth pressure cells at pier-soil and raft-soil interfaces. Testing results shows that this type of foundation can result in economical advantages with respect to optimized load transfer to the subsoil, which have been successfully applied to a building foundation design in Shenyang.
