摘要
对地铁车站设计中受到规划的影响,与市政变电站合建成超大基坑设计进行了分析,从地质情况、周围环境要求、工程功能、当地的常用施工工艺设计以及经济技术条件方面进行了论述,提出了超大基坑方案采用地下墙和桁架支撑支护体系方法,达到了在工程实施中经济合理性,保证了超大基坑安全实施;解决了桁架支撑体系的方案设计和分析理论计算与实际监测数据对比的问题。
The design of metro station is affected by planning,and the design of large foundation pit is analyzed with the municipal substation.The paper discusses the geological condition,the surrounding environment,the engineering function,the local common construction process design,in addition the economic and technical conditions. The method of the diaphragm wall and truss supporting system is proposed. It has achieved the economic rationality in the implementation of the project and ensured the safe implementation of the large foundation pit. The design and analysis of the truss support system solved the comparison between the theoretical calculation and the actual monitoring data.
