| 摘 要： | 提出了一种作用沉入式大直径圆筒内，外壁上的土体竖向切力模型，该模型假设土体的竖向剪切变形刚度系数与土中深度和筒体位移成比例，得到了求解筒体位移的平衡方程为一非线性方程组，为此建立了求解这一方程组的迭代算法，并用模型试验结果对其进行了检验，计算结果与试验结果吻合较好。

| Abstract: | This paper presents a model of the vertical shear which acts on the soil body inside and outside a large diameter cylinder.It is assumed that the shear deformation stiffness constant is proportioanal to the depth under soil and displacement of the cylinder.The equations of equilibrium for solving the displacements are nonlinear,therefore an iterative approach to solving the equations is developed.It is verified through model tests. |
