    摘要基坑支护是指在基坑的侧壁及周边环境采用支档、加固与保护等措施,它在基坑工程中是十分重要的一环节。本课题是研究苏州市平江区行政中心基坑工程的开挖支护设计方案。苏州市平江区行政中心总用地面积为39175m2,总建筑面积为83464.2 m2,地下车库总建筑面积为18040 m2。拟建工程建筑物包括平江行政中心,行政服务中心及市民文化活动中心,以及人民检察院及人民法院大楼各1幢,设大范围一层地下室。结构底板埋深为室外整平地坪标高以下5.40m左右,挖深为现地面以下3.50~5.20m不等。 52537

    结合基坑开挖深度、周边环境和地质水文条件,在保证基坑安全和经济合理的原则下,综合考察现场的周边环境、道路及岩土组合等条件,尽可能避免基坑开挖对周围建筑物、道路的影响。经过分析及对方案进行比较,在保证基坑安全和经济合理的原则下,结合本工程的特点,决定采取放坡+土钉墙支护。对于基坑降水排水,采用轻型井点管降水及集水坑排水。

    Abstract

    Foundation Pit Support in the side wall of the pit and the surrounding environment backgage, strengthening and protection measures, it is a very important link in Foundation. This topic is researching the engineering design plan of foundation pit excavation and support in the administrative center of Pingjiang district, Suzhou

    The administrative center of the total land is an area of 39175m2 in Suzhou Pingjiang.  Its total construction is an area of 83464.2 m2. Its underground garage with a total gross floor is an area of 18040 m2.Building of the proposed works including Ping Jiang Xingzheng Center, Administrative Service Center, and members of the public cultural activities center, as well as the People's Procuratorate and the People's Court building each one, and will set up a wide range of layer basement. The depth of the structural floor for the whole of the ground floor elevation below the outdoor is about 5.40m. The below ground is deepened 3.50 ~ 5.20m.

    Combining with the depth of the foundation pit excavation, the surrounding environment and the geological and hydrological conditions in the basement safety and economic rationality principle, comprehensive survey of the scene surrounding environment, roads and geotechnical combination conditions, as much as possible to avoid by foundation pit excavation the affecting of the surrounding buildings and roads.After analyzing and comparing the schemes , ensuring the safety of the pit ,as well as economical and rational .combining the characteristics of this project. I decide to take the slope setling design and soil nail support. The dewatering and drainaging of the pit ,I decide to take the light well point drainage ,and use the drainage sump to draining.

    Keywords:  foundation pit ; support ; slope ; soil nail support
