针对自平衡法试验数据的分析处理,假定桩侧土荷载传递函数符合三折线模型,考虑桩身重力作用的影响,推导出上段桩荷载-位移曲线的解析算式,并给出了由自平衡法试验数据确定桩 土参数的方法.通过2根桩的实测数据初步验证了文中解法的适用性,为由自平衡法试验数据推算桩侧摩阻力和桩身参数、常规顶压桩的荷载-位移曲线提供了一种理论手段.
A set of analytical equations of the loading-displacement curve of upper pile segment for the O-cell pile testing(OPT) method were established by using load transfer method.The lateral soil of pile shaft was simulated with a tri-linear load-transfer function and the gravity of pile shaft was taken into account.Also,the method to determine parameters for the pile-soil system with OPT data was mentioned.The theoretical results were compared with engineering cases from literatures.The method could be used as a...
