| 摘 要： | 研究了扭矩作用下单桩的扭转变形.采用积分变换和传递矩阵方法,求解了成层土在内部环形荷载作用下的基本解;利用此基本解并考虑桩土位移协调条件,提出了层状地基中单桩扭转变形分析的解析方法;并按此理论方法对匀质地基模型进行了数值计算,其结果与已有经典解答相当吻合.

| Abstract: | An analytical method is developed to analyze the torsional response of a single pile embedded in a layered soil. The fundamental solutions for displacements and stress components of the layered soil due to unit internal ring loading are first derived with integral transforms and the transfer matrix method. These solutions are then combined with the displacement compatibility between the pile and the surrounding soil to analyze the torsional behaviour of a single pile. Numerical results for the special case of a homogeneous isotropic elastic semispance are presented and show good agreement with the existing solutions. |
