摘要
针对深基坑中支撑结构难以计算的问题,介绍了钢结构支撑布置的基本原则及支撑体系算法中的连续梁法。以杭州地区最具代表性的某基坑工程为算例,根据地质条件计算出土压力的分布情况,采用连续梁法计算支撑内力,确定支撑计算长度、立柱设计、对撑设计,根据内力和基坑跨度大小采用STS软件设计出一套标准化通用格构式钢结构支撑体系。以期对今后的工程计算起到一定的借鉴作用。
In view of the problems about how to calculate the steel structure support, the paper introduces the basic principle about the arrangement of steel braces and the method of continual beam as one of the support system algorithms. Taking the most representative foundation pit in Hangzhou area for an example and according to the geological condition, the author computes distributed situation of soil pressure, and uses the method of continual beam arithmetic support internal force to determine the braces computation length and the column design as well as the design of symmetry braces. By using software STS, a set of standardization general lattice steel braces system is designed according to the internal force and the span of the foundation pit. Thus this can be used for reference to the projection computation in the future.
