摘要：根据项目实际情况进行研究设计，方案要求合理，经济，安全，符合规定要求，满足基坑设计要求，地铁站功能要求。使用理性深基坑7.0，实施以下具体计算：设计比较，支撑结构计算和绘图，基坑稳定性检查，基坑停水设计，基坑监测程序设计，水（突然）检查，防提升检查，抗倾覆稳定性检查，士壤稳定性计算，坑底士体反应检查的嵌入段。在此基础上加固，绘图施工图纸。

  通过比较行支撑和连续墙支撑的两种方法，从经济和安全综合分析，建议基坑设计采取连续墙支撑，提出完整的设计方案。68809

Shenzhen Loajie subway station support design of foundation pit 

Abstract: According to the actual situation of the project carried out research and design, the requirements of the program is reasonable, economical, safe and meet the regulatory requirements, to meet the requirements of the design of the foundation pit, Subway station functional requirements. The use of rational deep foundation pit 7.0, the implementation of the following specific calculations: design comparison, support structure calculation and drawing, foundation pit stability checking, foundation pit water stop design, foundation pit monitoring program design, Water (sudden) check, anti-uplift check, anti-overturning stability check, soil stability calculation, embedded section of the pit foundation soil reaction check. On this basis, reinforcement, drawing construction drawings.68809

    Through the comparison of the two methods of row support and continuous wall support, from the comprehensive analysis of economy and safety, it is recommended that the foundation pit design should adopt continuous wall support and put forward the complete design scheme.

KeyWords: Pile support; continuous wall support; rational deep foundation pit 7.0 software; foundation pit design
