| 摘 要： | 对桩侧土采用非线性荷载传递函数,对桩端土采用线性荷载传递函数,同时考虑桩周土所分担的荷载对单桩荷载传递规律的影响,利用增量荷载传递矩阵法及微分方程的近似解法--子域法,推出了刚性承台下柔性桩与地基非线性相互作用的近似解析算式。为了验证该方法的可行性,通过试验将试验结果与有限元结果及该方法所得结果进行了对比,对比表明:该理论解与现场实测值、有限元计算值都非常接近。

| Abstract: | Based on nonlinear load transfer function to pile-side soil linear load transfer function to pile-soil,considering influence of sharing load of the pile-side soil on load transfer law of piles,and using the transfer matrix method of increment load and the approximate solution method-district method of differential equation, a set of approximate analytical formulas of nonlinear interaction for the flexible pile and soil are derived under rigidity bearing platform. In order to verify the reliability of the proposed method,the test results are compared with the results of the finite element and the proposed method in this paper. Contrast enunciation that the proposed method has good precision. |
