永丰路站为已建成的地下三层地铁车站,将车站上盖物业开发地下室深基坑一分为二。车站两侧深基坑实施与既有地铁车站存在强相关影响,突出表现在深基坑施工过程引起地铁车站的侧向位移与结构隆起,而这种影响对地铁开通运营后不容忽视,因此结合地铁开通时间,进行工程实施的总体策划,将基坑实施对地铁运营影响降至最低点。本文对车站两侧深基坑实施进行了详细的分析策划,并就实施过程对地铁车站的强相关影响进行了多种方法的对比分析,分析研究深入细致,较准确的掌握了影响规律及影响程度并提出了切实可靠的技术路线与技术措施,切实解决了对既有地铁车站的保护问题,具有强烈的现实意义和借鉴意义。
Yongfeng Road Station has been completed underground three subway stations, the basement of the station covers the property development basement deep into two. The deep foundation pits on both sides of the station are strongly related to the existing metro stations. The outstanding performance is caused by the lateral displacement and structural uplift of metro stations during the construction of deep foundation pits, which can not be ignored after the subway is opened and operated. Therefore, The opening hours of the MTRC will carry out the overall planning of the project implementation and minimize the impact of the implementation of the foundation pit on the MTR operation. In this paper, the detailed analysis and planning of the deep foundation pit construction on both sides of the station are carried out. A comparative analysis of various methods is made on the strong correlative influence of the subway station on the implementation process. The analysis and study has thoroughly and carefully mastered the influence laws and influences And put forward practical and reliable technical routes and technical measures to effectively solve the existing subway station protection problems, with strong practical significance and reference.
