摘要
为研究自平衡试桩对传统静压桩的荷载-位移转换问题,基于简化转化法,对比研究了等位移条件下的荷载位移转换法和等荷载条件下的荷载位移转换法。在相同条件下进行静压桩和自平衡桩的室内模型试验研究,研究结果表明,当自平衡桩上下段桩同时破坏时,采用等荷载转换法精度高于等位移转换法。等荷载转换法的转换结果更接近静压桩,极限承载力转换结果的误差为3%。
In order to study the transfer of load-displacement from self-balanced test pile to traditional static pressure pile, based on the simplified transformation method, the load displacement conversion method under the equal displacement condition and the load displacement transformation method under the same load condition are compared. Laboratory model test of static pressure pile and self-balanced pile under the same conditions are carried out. The results show that when the upper and lower sections of the self-balanced pile is destroyed at the same time, the accuracy of the equal load transformation method is higher than that of the equal displacement transformation method. The transformation result of equal load conversion method is closer to that of static pressure pile, and the error of ultimate bearing capacity conversion result is 3%.
