桩筏基础空间桁架模型的方案设计与现场试验分析

摘要

本文对一试点工程桩筏基础按空间桁架模型进行了方案设计和现场测试，并对测试结果进行分析。结果表明，空间桁架理论适用于桩筏基础设计，并且是安全可靠的。%The pile-raft foundation of a pilot project was designed by space truss theory and on-site testing was carried out.Test data are analyzed subsequently and the analytic results indicate that the space truss theory is suitable for design of pile-raft foundation on the safe side.
