刚性桩改良地基基础试验研究与数值分析

Study on Test of Rigid Foundation Improvement Pile and Finite Element Analysis

文章通过某高层建筑基础现场测试结果,对刚性桩改良地基的承载力特性,结构沉降以及筏板钢筋受力等状况做了分析和研究.然后将实验结果与相应的数值分析结果进行对比,为进一步完善刚性桩改良地基基础的设计理论提出了建议。研究结果表明数值分析对理论研究和工程设计具有重要的参考价值。

Through test results of a high-rise building＇s foundation, the mechanical characteristics of rigid foundation improvement pile, the settlement of the foundation and the stress distribution in raft and rebar were researched. And then the test results were compared with the results of finite element analysis. Finally, some suggestions for design theory of rigid foundation improvement pile were proposed. The test results combined with numerical results are of great reference value for theory research and project design.
