摘要：本课题针对深圳地铁三号线老街站基坑支护工程进行设计。深基坑支护的设计、施工、监测技术是近10多年来在我国逐渐涉及的技术难题。所以我们利用理正深基坑7.0软件进行电算。根据工程的实际情况，对深圳地铁三号线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。22869
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。
通过对连续墙支护设计，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 Metro three Line Street station deep foundation design
Abstract：This topic on the old street station foundation pit supporting project of shenz-hen metro line no. 3 to carry on the design.Deep foundation pit supporting design, construction and monitoring technology is involved in recent 10 years in our country gradually. So we using Lizheng deep foundation pit 7 comput-er software. According to the engineering actual situation, to the old street station found-ation pit supporting project of shenzhen metro line no. 3 to carry on the research and d-esign,design reasonable, economy, safety, compliance with the specification requirement-s, meet the functional requirements of subway station.
The specific election than to complete the design calculation and drawing; supporting stru-cture; foundation stability; precipitation sealing design of foundation pit; design of foundati-on pit monitoring programme; anti-uplift checking; anti overturning stability check; emb-edded inside of pit soil counterforce calculation. The Lizheng deep foundation pit 7 softwar-e applications is very important, it can calculate most of data and calculation of power, an-d the reinforcement and construction drawing.
Through the continuous wall supporting design, comprehensive analysis from the econo-mic and security, recommend this project design USES continuous wall supporting of fo-undation pit, and put forward a complete design scheme.
Key Words： Foundation pit supporting；continuous retaining wall；7.0 software of Lizheng deep foundation pit
