本文将多用途水工船的作业稳性问题化为同时承受分布荷重、轴向力、水平力及弯矩的固定桩的承载力问题.在此基础上给出轴向容许承载力计算公式,用解析法分析地上部分的固定桩,求出地面处的内力与位移,并以此为初始条件采用迁移矩阵法对土中部分桩进行分析,从而得到整个固定桩的位移与内力.最后给出了水工船作业稳性标准.
In this paper, the operational stability of multi-purpose watercrafts is transformed into the problem of bearing capacity of fixed piles that simultaneously bear distributed loads, axial forces, horizontal forces, and bending moments. Based on this, the calculation formulas for axial permissible bearing capacity are given. The analytic method is used to analyze the fixed piles in the aboveground part, and the internal forces and displacements at the ground are obtained. Using this method as the initial condition, some piles in the soil are analyzed using the transfer matrix method to obtain the displacement and internal force of the entire fixed pile. The hydraulic ship operation stability standards.
