PHC管桩承载力试验分析

为了研究驻马店地区PHC管桩承载力特性,文章依据该地区某工地PHC管桩沉桩施工资料,将其静载荷试验结果和沉桩终压力进行了对比分析,得出桩实际承载力要比设计高出许多,结果表明预应力管桩基础在静压时对于中高压缩性土,应以桩长控制为主,压桩力为辅的原则进行施工,以便确定其承载力,进一步在工程应用中进行合理的设计、施工。

Analysis on loading test of PHC pipe pile

In order to study the loading capacity features of the PHC pipe pile in Zhumadian area,according to the construction information of the PHC pipe pile sinking pile in a construction place of Zhumadian area,the paper had made a comparison analysis on the static loading test results and the sinking pile final pressure.The analysis results showed that the actual loading of the pile was much higher than the designed.The results showed the pre-stressed pipe pile base in the medium and high compressed soil should mainly control the pile depth and should take the principle of pile pressing force as the auxiliary to make the operation in order to determine the loading force for the rational design and construction of the future project application.
