摘要
青秀山地铁车站站厅基坑采用明挖和排桩内支撑的支护形式,周边环境相当复杂。对基坑支护结构、基坑周围土体和相邻建筑物进行全面系统的监测,在出现异常反应时及时反馈,进行施工工艺的调整,结合基坑开挖的实际情况,利用有限元软件进行数值模拟,来分析基坑开挖对建筑物沉降的影响,并结合实际监测数据给出最合理的防护措施并为同类深基坑提供参考。
The foundation pit of Qingxiushan subway station is supported by open excavation and internal support of row piles, and the surrounding environment is quite complicated. The retaining structure of the foundation pit, the soil around the foundation pit and the adjacent buildings are monitored comprehensively and systematically. In the event of abnormal reaction, timely feedback is made, the construction technology is adjusted, and combined with the actual situation of the excavation of the foundation pit, The finite element software is used to simulate the influence of foundation pit excavation on the settlement of buildings, and the most reasonable protection measures are given in combination with the actual monitoring data, and the reference for similar deep foundation pit is provided.
