摘要
文章以成功的基坑工程圆环支撑系统设计实例为基础,对圆环支撑优于直杆型支撑的结构、施工特性作出比较细致的分析,得出如果圆环支撑运用得当,可以实现投资减少、工期缩短、位移减小的目标。同时又对采用圆环支撑应注意的问题进行了探讨,为圆环支撑设计提供有益的参考。
In this article, basing on successful instances of design of foundation pits with arch brace, the superiority of arch brace to normal brace concerning structural and construction characteristic is analyzed. It is concluded that decreasing investment, shortening construction time and lessening displacement can be resulted thus providing reference for applying arch brace appropriately.
