内撑式支护结构内力、变形的性状分析

Analysis of Internal Force and Deformation of the Retaining Structure with Struts

将内支撑式支护结构假设为带桩的框架结构，计算了其内力、变形，并对其性状进行了分析。重点对支护结构的刚度方程进行详细推导，并给出了相应子程序。通过算例对内支撑长度、刚度对支护结构内力与变形的影响进行了探讨。

The retaining structure with struts is presumed pile - frame structrue, the internal force and deformation are calculated, the behavior of the structure is also analysed under influence of bracing length and rigidity of the struts.
