某高层建筑无支护基坑稳定性研究

Study of Stability of the Foundation Pit without Any Support

介绍了采用无支护结构工程技术太原市某高层住宅楼基坑开挖是的实例,重点阐述了无支护情况下基坑稳定性的计算,并分析了原因。采用无支护结构开挖基坑,既满足了工程需要,缩短了工期,又带来可观的经济效益,但在类似工程中推广还需一定的工程经验积累。

In this paper the author introduces an example of the practice on application of foundation pit without any support of a tall residential building in Taiyuan. The main points in calculation of stability of the foundation pit without any support is elaborated. It points out that the pit without any support in the engineering example not only meets demands of stability of the foundation pit, but also is economical in time and cost. Hoverer, it needs more experience in the similar profects.
