【摘要】 基于弹性地基梁法,采用"矩形分布"模型,将基坑底部以下被动土压力看作弹簧支座。建立桩锚支护结构内力及位移分析的哈密顿求解体系,利用两端边值问题的精细积分法中的区段混合能矩阵及边界条件推导边界其他未知广义位移及广义力,然后用边值问题的精细积分法对桩进行分析,并用Matlab语言编制相应的分析程序,最后通过实例分析验证该方法的可行性。更多还原

【Abstract】 On the basis of elastic reaction method and adopt"rectangle distribution"model,establish the Hamiltonian dual system for internal force and deformation analysis of piles-anchor retaining structure.The high-precision integration method of two end boundary conditions was adopted to realize the high-precision numerical solution of the system by means of computer programmers with Matlab.The reliability and feasibility of this method is testified through an example.更多还原
