| 摘 要： | 基坑支护等值梁法的力学模型可视为插入端为固定端，锚固点为铰的超静定计算模式，但计算繁复。以VC 为开发环境实现的基坑支护等值梁法，使用关系型数据库Access建立与基坑开挖相关的工程地质资料，通过人机交互获取分层支护设计条件，以等值梁法计算基坑各开挖阶段最大弯矩值和锚固处反力值，直观地绘制出设计开挖工况视图，最终求出墙的插入深度。程序设计和算法具有快速、准确和易操作等优点，从而提高了支护设计的效率，避免了因设计不合理而重复计算所引起的人力、物力和时间上的浪费。

| Abstract: | The mechanics model of equivalent beam method is staticlly indeterminate that supposes the insert end as step shaft and the anchor point as pivot point. But the calculation is complicated. The program designed with Visual C++ language sets up engineering geology data about excavation through Access,a relation database. It gets designed excavation conditions through interactive manner, calculates the max moment and resistance of anchor points of different excavation stages, draws designed excavation situation, and obtains the depth of wall. The program presents accuracy, rapidness and maneuverability for improving efficiency and preventing the waste of labor, material and time because of irrational design. |
