摘要随着我国城市化建设的发展，近年来全国各地建筑深基坑支护工程发展很快,因建设需要，地下空间开发要求愈来愈高,其支护结构难度也愈来愈大,已成为高层建筑基础工程中的难点和热点。本文结合镇江御带河花园2#地库基坑进

行支护方案设计，主要工程如下：51280

 简要介绍目前常用基坑支护结构形式及适用条件。

 分析工程特点，确定支护结构形式。场地位于禹山东路以西，学府路以北。东侧道路安全运行对基坑变形要求较高，考虑上述因素，确定支护总体方案排桩加上混凝土支撑结构形式。

 采用理正深基坑支护设计软件进行支护结构单元计算。

 绘制施工图，包括周边环境图、支护结构平面布置、支护结构剖面及节点大样图。

 明确涉及支护结构形式施工工艺要求，针对基坑周边环境保护要求，确定基坑监测报警值及监测要求。

Abstract In recent years,with the development of city construction, construction of deep foundation pit supporting project development throughout the country soon,due to the needs of construction,Underground space development rising demand,It also makes it harder for the supporting structure of a greater. Has become the Foundation of high-rise building's difficulty and hot spots. This article combines Zhenjiang Garden of River Royal 2# library design of Foundation pit supporting scheme,Main projects are as follows:

 Briefly describes common forms of support structure of Foundation pit and its applicable conditions.

 Analysis on engineering characteristics, determine the form of supporting structure. Venue is located in Shandong, Yu Road West of xuefu road north of. East side runs road safety higher on deformation of Foundation pit, Considering the above factors, determine the overall programme of support pile combined with concrete supporting structure.

 Lizheng software for design of deep Foundation pit retaining structure calculation.

 Draw shop drawings, including the layout of surrounding environment, supporting structure, cross section of support structure and node detail drawing.

 Deal expressly with the supporting structure construction technology requirements for around Foundation pit protection requirements, determine the Foundation pit monitoring alarm and monitoring requirements.
