摘要
本文在一根基桩中同时得到桩的抗拔与抗压极限承载力,采用双荷载箱自平衡试验方法。通过先后打开上下荷载箱得到相关试验数据,分别采用简化计算方法与精确转换方法探讨双荷载箱下自平衡测试结果的转化方法,得到相关的转化曲线。进一步对比分析两种方法计算结果的差异,寻求合理的双荷载箱下自平衡测试结果转换方法。
In order to get the ultimate uplift bearing capacity and the ultimate compressive bearing capacity in one foundation pile test at the same time,the method of self-balanced pile test under double load cells was used for the experiment.The relevant test data was got by opening the two load cells in turn.There are simplified calculation method and precise conversion method to be used to research the test data of the method of self-balanced pile test under double load cells to get the relevant conversion curve.The further comparative analysis of calculation result differences by the two kinds of methods is of vital importance to research the reasonable conversion method of the method of self-balanced pile test under double load cells.
