| 摘 要： | 介绍用深层搅拌桩支护基坑的设计与施工方法.深层搅拌桩在我国建筑工程中不仅用于地基加固,而且在基坑支护中也得到了广泛应用.但当地基情况太差,基坑较深或场地较窄时,该工法就受到一定限制.笔者通过多次学习与实践,认为增加槽底加固桩可扩大其使用范围,并可大幅度降低工程造价.

| Abstract: | This paper introduces the design and construction method of foundation pit supporting with Deep Mixing Cement Piles(DMCP). The DMCP is adopted widely not only in ground improvement but also in supporting structure of pit, but when the condition of ground is worse, or the excavation of foundation pit is deeper, or the area of site is smaller, the application of the DMCP is limited in certain extent. The author summarised in the study and practice that the DMCP application can be extended by increasing the number of braced piles in the bottor of pit, and the cost of engineering can be decreased largely. |
