1、 I 南京某地铁车站维护结构设计 摘要 基坑工程是为保证基坑施工、主体地下结构的安全和周围环境不受损害而采取的支 护结构、降水和土方开挖与回填，包括勘察、设计、施工、监测和检测等的一项综合性 很强的系统工程。基坑工程是土力学基础工程中一个古老的传统课题，同时又是一个综 合性的岩土工程问题。随着基坑的开挖越来越深、面积越来越大，基坑围护结构的设计 和施工越来越复杂，所需要的理论和技术越来越高。 深基坑工程涉及结构工程、岩土工程和环境工程等众多学科领域，综合性高，影响 因素多，设计计算理论还不成熟，在一定程度上还依赖于工程实践经验。 本文在第一章中介绍了深基坑的发展状况、人们对其设计理论的研究状况

2、及重点研 究方向。第二章介绍了本工程的工程背景和工程的相关的地质条件及相关的土层参数。 第三章通过基坑特点的分析及维护方案选择的原则确定了本工程的基坑支护方案。第四 章主要进行了基坑围护结构的计算，包括土压力的计算，支撑内力的计算，维护结构的 配筋计算，支撑结构的配筋计算等内容。第五章初步讨论了该工程的施工方案。第六章 简要的论述了关于该基坑施工质量保证措施相关内容。 关键词：基坑工程关键词：基坑工程 , ,基坑维护基坑维护, ,施工施工 II MAINTENANCE DESIGN OF NANJING METRO STATION STRUCTURE ABSTRACT Foundation p
