针对现行的《公路桥涵地基与基础设计规范》在横向受荷桩计算分析中无法对地基分层、桩侧土地基比例系数变化或桩身抗弯刚度变化直接解答等缺点,将传递矩阵法引入横向受荷桩的结构计算分析中.根据线弹性地基反力法的基本原理,将桩划分为若干单元并将其简化为多点弹簧支承的连续梁,利用材料力学的知识求得结点之间状态向量的传递关系及桩的总体传递矩阵;根据桩底边界条件,求得桩顶的初始状态向量.通过实例分析与其他计算方法比较,结果表明该法可有效地解决现行规范计算方法存在的不足之处.
According to the current “Code for Foundation Design of Highway Bridges and Culverts”, the transfer matrix method can not be introduced in the calculation of lateral loading piles because of the failure of stratification of foundation, the change of proportion coefficient of foundation soil on piles or the direct response of pile bending stiffness variation. According to the basic principle of the linear elastic foundation reaction force method, the pile is divided into several units and simplified to the multi-point spring-loaded continuous beam, the knowledge of the material mechanics is used to calculate the node The relationship between the state vector and the overall transfer matrix of the pile, the initial state vector of the pile top is obtained according to the boundary conditions of the pile bottom.Compared with other calculation methods, the results show that the method can effectively solve the problem of the existence of the existing standard calculation method Deficiencies.
