摘　　要：等值梁法是目前基坑支护系统中常用的计算方法。但是,此法对带多支撑的基坑支护的具体设计计算却很少。针对山西省昔阳县政府服务大楼的基坑,采用桩锚支护,按等值梁法并结合连续梁法对多支撑支护结构进行具体的设计计算,并对整个设计过程进行了详细的分析,得出可用于工程实践的设计结果。计算过程清晰易懂,适用性强,安全性高。At present,the equivalent beam method is the most popular method which is used to support the foundation pit.But for the pit multi-braced,there are few concrete calculations with this method.Taking the foundation pit of the services building in Xiyang Country of Shanxi Province as an example,the pile-anchor support structure was adopted,and the concrete calculation to the multi-braced structure with the equivalent beam method and the continuous beam method have been conducted.In addition,the whole calculating process has been analyzed.Finally,the results which can be used to the real project have been achieved.The whole process shows the designing principle clearly and makes people understood easily,so it has great applicability and high security.
