摘要：本课题针对深圳地铁老街站进行设计，利用理正深基坑7.0软件进行电算。根据工程的实际情况，对深圳老街站基坑支护工程进行研究与设计，要求设计方案合理、经济、安全，符合规范要求，满足地铁站功能需求。30017
     运用理正深基坑7.0软件，进行了以下计算：设计方案比选，支护结构计算与绘图，基坑稳定性验算，基坑的降水止水设计，基坑监测方案设计，抗承压水(突涌)验算，抗隆起验算，抗倾覆稳定性验算，嵌固段基坑内侧土反力验算等。在此基础上进行配筋，得到施工图。
通过对排桩支护和连续墙支护两种方法的对比设计，从经济和安全综合分析，推荐本工程基坑设计采用连续墙支护，并提出了完整的设计方案。

Shenzhen Loajie subway station  support design of foundation pit
Abstract：Shenzhen Loajie subway station pipeline foundation support engineering design, using Lizheng deep foundation pit 7 computer software. According to the actual situation of project, the Shenzhen Loajie subway station District Avenue pipeline excavation engineering research and design requirements, design reasonable, economy, safety, compliance with the specification requirements, meet the functional requirements of subway station.
The specific election than to complete the design calculation and drawing; supporting structure; foundation stability; precipitation sealing design of foundation pit; design of foundation pit monitoring programme;  anti-bearing water (surge) checking; anti-uplift checking; anti overturning stability check; embedded inside of pit soil counterforce calculation. The Lizheng deep foundation pit 7 software applications is very important, it can calculate most of data and calculation of power, and the reinforcement and construction drawing.
Among many methods of foundation pit, select the row of the design pile supporting and two
methods of continuous wall supporting, and comparing the two, sum up the advantages and disadvantages, convenient principle and understand the difficulties of foundation design more deeply, and more economical construction.
Key Words： row pile retaining；continuous retaining wall；7.0 software of Lizheng deep foundation pit
