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 the planning, and the design of large-scale foundation pit combined with municipal substation is analyzed. The paper discusses the geological conditions, surrounding environment requirements, engineering functions, local common construction technology design and economic and technical conditions The scheme of supporting large-size foundation pit with underground wall and truss supports the supporting system, which achieves the economic rationality in project implementation and ensures the safe implementation of extra-large foundation pit. The scheme design and analysis of truss support system are solved. Theoretical calculation and actual monitoring data Contrast problem.
