【摘要】：隨著城市建設(shè)步伐的加快,不可避免地會(huì)出現(xiàn)鄰近地鐵線路的多個(gè)基坑同時(shí)施工的情況。為確保既有地鐵線路結(jié)構(gòu)及運(yùn)營(yíng)安全,有必要研究鄰近地鐵線路的多個(gè)基坑同時(shí)開挖對(duì)地鐵線路結(jié)構(gòu)產(chǎn)生的疊加效應(yīng)。上海長(zhǎng)泰國(guó)際廣場(chǎng)項(xiàng)目和浦東軟件園三期A1地塊綜合商業(yè)配套項(xiàng)目分別位于上海軌道交通2號(hào)線金科路站兩側(cè),兩個(gè)項(xiàng)目的基坑同時(shí)施工,對(duì)比分析了施工階段對(duì)樁基、圍護(hù)、加固、基坑開挖、地下室回筑等進(jìn)行監(jiān)測(cè)的數(shù)據(jù),在此基礎(chǔ)上分析了鄰近基坑開挖對(duì)2號(hào)線金科路站車站及附近隧道結(jié)構(gòu)變形的疊加效應(yīng),并制定了有效的監(jiān)護(hù)方案及防護(hù)措施。
[Abstract]:With the acceleration of urban construction, it is inevitable that several foundation pits adjacent to subway lines will be constructed simultaneously. In order to ensure the structure and operation safety of the existing subway lines, it is necessary to study the superposition effect of excavation of several foundation pits adjacent to the subway lines on the subway line structure at the same time. The Shanghai Changtai International Plaza Project and Pudong Software Park Phase 3 A 1 comprehensive commercial matching project are located on both sides of Jinke Road Station of Shanghai Rail Transit Line 2, respectively. The foundation pit of the two projects is under construction at the same time. Based on the monitoring data of reinforcement, foundation pit excavation and basement back construction, the superposition effect of adjacent foundation pit excavation on the deformation of Jinke Road Station and adjacent tunnel structure on Line 2 is analyzed. The effective monitoring scheme and protective measures are also worked out.
