数值迭代法用于基坑支护空间结构设计

Numerical Iteration Method Adopted for Space Structural Design of Foundation Pit Supporting Protection

探讨采用数值迭代法对深基坑支护的设计。该法采用平面杆系有限元分别计算板桩和支撑系统的受力和变形。本文主要介绍该法的电算程序包及其计算实例，从而说明该程序有较好的精度及实用性，可作为基坑围护工程设计中结构内力和变形计算的计算机辅助设计。

Numerical iteration method adopted for design of deep foundation pit supportingprotection is discussed. The method adopts plane rods limit-element to calculate the forceand deformation of slab pile and supporting system separately. It mainly introduces thecomputer programe kit and calculation examples, which shows that this programe possesseshigher accuracy and better practicality, and thus may be adopted as computer-aided designfor calculation of structural internal force and deformation of foundation pit supportingprotection project design.
