水泥搅拌桩在两层地下室基坑支护中的应用

Application of cement Mixed-pile in two-story Basement pit supporting

本文通过在两层地下室基坑中应用水泥搅拌桩-锚杆支护结构的工程实例,阐述了该类型支护结构计算原理和方法,以及采取的控制措施,取得良好效果,该工程布置了较完善的变形监测系统,测试资料全面、完整,对于判断支护结构安全性,对于研究和应用具有重要意义,本工程取得的经验对于类似工程具有指导意义。

Through the construction example of application of cement mixed - pile combined anchor bolt in pit supporting of a two - story basement, this paper explicated calculated principle and method of such pit supporting structure, It also introduced the applied control measures and its good effect. The construction mention aboved also arranged rather, perfect deformation monitoring system and the testing data were full scale. Complete it was significant for judgement of salty of supporting structure and was important for research and application.
