第一章 总体概述
1.1 工程概况
工程名称：常州九龙仓·国宾花园人防地下室（Ⅰ区北侧）基坑支护工程 建设单位：九龙仓（常州）置业有限公司 勘察单位：常州市基础工程公司
支护设计单位：常州市华泰岩土工程有限公司
建设地点：常州市新北区新北区河海东路北侧、藻江河西侧 基坑开挖深度：4.90～5.40m
工程内容：施工图范围内基坑支护工程
1.2 编制依据
（1）《岩土工程勘察报告》
（2）总平面图、基础图；（甲方提供）
（3）常州市华泰岩土工程有限公司：基坑支护设计方案及图纸； （4）《建筑基坑支护技术规程》（JGJ120-99） （5）《建筑地基基础设计规范》（GB50007-2002）
（6）《建筑地基基础工程施工质量验收规范》（GB50202-2002） （7）其它有关规范。
1.3 周边环境
拟建地下室周边为在建的住宅楼、商业及施工场地。本次支护设计的范围为Ⅰ区地下室的北侧基坑，即沿1-M轴从1-4轴至1-33轴。该范围北侧有一施工道路，距坑边（坡底）2.5～4.2m，3倍基坑开挖范围无内与本工程相关的管道及管线等障碍物。
1.4 基坑支护形式
根据设计文件，本支护工程支护形式分为二种，AB段采用放坡支护形式，坡比为1:0.6，坡面喷射砼；BC段采用土钉墙，按1:0.3放坡开挖，施工3排土
