深基坑水泥土墙的应用分析

Analyses of Cement Mixed Walls in Deep Excavations

深基坑支护结构形式和设计计算的方法很多,如何合理选取是值得研究的问题。结合工程实例,根据水泥土墙的特点,以及工程地质条件和周围环境,对基坑开挖进行了可行性和稳定性分析,并对水泥土墙在工程中的应用进行了探讨,供相关工程参考。

With the rapid urban developments, more and more high-raised buildings are constructed in the limited urban areas. There is a trend to utilize the underground spacing for these high raised buildings. As a result, the supporting demand for the deep excavation is ever increasing. There are many supporting techniques and their associated design methods available. For a specific deep excavation project, the selection of the supporting method and the appropriate design method are among the first objective. This paper presents a case history of using the cement mixed wall for a deep excavation supporting system. The subsurface conditions, the adjacent construction environment for the proposed deep excavation site as well as the stability analysis of the proposed excavation are introduced.
