Anti-uplift construction method for subway station body structure in construction adjacent to subway foundation pit
The invention discloses an anti-uplift construction method for a subway station body structure in construction adjacent to a subway foundation pit, and relates to the technical field of foundation pit construction, and the method comprises the following steps that S1, before construction, numerical simulation inversion analysis is carried out on subway excavation uplift deformation in combination with a station upper structure load requirement and a station structure condition; S2, loading simulation is carried out on the station, and loading measures are determined; S3, in the excavation process of the foundation pit, the upper portion of the station is loaded step by step according to the formulated loading measures; and S4, after pile loading is completed, construction of the underground structure main body structure is completed. According to the anti-upheaval construction method for the subway station body structure in the construction adjacent to the subway foundation pit, the construction cost is relatively low, the operation flexibility is high, the upheaval amount of a subway structure and an interval tunnel can be reduced, and the safety of the tunnel structure and the normal operation of a subway train can be fully guaranteed.
本发明公开了一种紧邻地铁基坑施工中地铁站体结构抗隆起施工方法，涉及基坑施工技术领域，包括如下步骤：S1、施工前，结合车站上部结构荷载要求以及车站结构情况，对地铁开挖隆起变形进行数值模拟反演分析；S2、对车站进行加载模拟，确定加载措施；S3、在基坑开挖过程中，根据所制定的加载措施，对车站上部进行逐步加载；S4、堆载完成后，完成地下结构主体结构施工。本发明提供了施工成本相对较低，作业灵活性较强，可以降低地铁结构及区间隧道的隆起量，并能充分保证隧道结构安全和地铁列车正常运营的一种紧邻地铁基坑施工中地铁站体结构抗隆起施工方法。
