以郑州1号线东明路站为例,分析了由于站位调整,车站在设计阶段以及在施工中可能会遇到的问题,并提出了解决方案。其中重点介绍了基坑周边雕塑“和谐之林”对基坑开挖的影响,通过监测点沉降计算与有限元分析,对建筑物的保护提出了要求;同时对基坑降水方案以及西侧端头井地墙接缝的处理方案作了较为详细的分析。分析表明:车站在调整站位以后遇到的设计难点和所采用的施工对策,需要综合考虑周围地质环境,既有或规划建(构)筑物的功能要求等,通过设计和施工紧密配合,采取安全、经济、方便施工的有效措施,以确保车站基坑顺利开挖。
Taking Dongming Road Station on Line 1 of Zhengzhou as an example, the problems that may be encountered due to station adjustment, station design stage and construction are analyzed and solutions are proposed. The paper mainly introduces the influence of the sculptures around the foundation pit and the forest of harmony on the excavation of the foundation pit. It puts forward the requirements for the protection of the building through the settlement calculation and finite element analysis of the monitoring points. At the same time, Side end of the well wall and wall joints of the treatment program made a more detailed analysis. The analysis shows that the design difficulties encountered by the station after the station is adjusted and the construction measures adopted by the station need to take into consideration the surrounding geological environment, the existing or planned functional requirements of the building, etc. Through the close cooperation of design and construction, Take effective measures that are safe, economical and convenient for construction so as to ensure the smooth excavation of the foundation pit of the station.
