摘要随着城市化过程中不断涌现的中高层和超高层建筑，以及对地下空间的开发，就产生了大量的深基坑。在基坑开挖过程中必然会涉及到基坑的支护，而基坑支护不仅会影响工程的进度，也会影响到工程安全，本论文主要对镇江科技园地下室基坑支护结构进行设计及稳定性验算。51286
镇江科技园总占地面积3000m2 ，基坑开挖深度都在6m左右，属于深基坑，基坑处地层主要有素填土、粉质粘土、淤泥质粉质粘土，基坑支护主要采用土钉墙工艺的支护桩进行支护。
本文先是介绍了深基坑工程的发展和现状以及我选择深基坑这个课题的目的和意义,通过对镇江科技园地下室基坑支护的设计,我选择了其中的两个剖面进行了详细的计算分析,然后通过理正软件分析了基坑整体的稳定性,最后我简单的介绍了一些土钉墙施工工艺及一些质量安全管理。

Abstract With the urbanization process, high-rise buildings and super tall buildings are continuously emerging, and underground space development project become more and more. As a result, it generated a lot of deep excavation projects. In the process of excavation, it inevitably involves the support of excavation pit. And the excavation will not only affect the progress of the project, it will also affect engineering safety. This paper mainly studies the design of supporting structure and stability computations of the Zhenjiang science park basement foundation pit.
The total area is about 3000 m2, excavation depth is about 6m, belonging to deep foundation pit. The foundation pit is mainly lime soil, salty clay, salty soil clip salty sand. Pit support mainly take soil-nail wall supporting technology.
This paper first introduces the development and status quo of deep foundation pit engineering, and I choose this topic the purpose and significance of deep foundation pits , through to the zhenjiang science park basement foundation pit supporting design, I chose the two section has carried on the detailed calculation and analysis, Then through the software analysis the whole stability of foundation pit, Finally, I simply introduces some construction technology of soil nail wall and some quality and safety management.
Keywords: deep foundation soil nailing wall supporting design stability
