摘要
SMW支护结构具有防渗性能好,构造简单,施工速度快,不影响周围环境,工程造价低等优点。根据多层支撑挡墙结构的常用分析方法,结合镇江市新河桥泵站基坑支护工程,论述了各种分析方法对SMW支护结构的适应性。
SMW retaining structure is of many good properties,such as good characteristics in watertight,simplicity in structure,quick construction,no effect on environment,low cost,and so on. According to the case of Xianhe bridge pump station in Zhenjiang,three structural analysis methods including the equivalence girder,the fixed supporting force of excavation and brace layer by layer and the elastic girder calculating method,are first introduced,and their fitness are then discussed. According to the calculating results,the fixed supporting force of excavation and brace layer by layer calculating method are comparatively suitable for practical construction.
