【摘要】：城市地鐵隧道施工中,有效保證鄰近管線的安全是工程的難點(diǎn)之一。文章以西安地鐵三號(hào)線通-胡區(qū)間為研究背景,采用FLAC數(shù)值模擬,得出了地鐵隧道暗挖施工對(duì)鄰近平行及垂直于隧道軸線的地下管線變形影響的規(guī)律;通過(guò)分析,預(yù)測(cè)了地鐵穿越地裂縫施工后管線的變形趨勢(shì),并提出了地鐵隧道下穿f4地裂縫的技術(shù)措施,以及地鐵暗挖施工中對(duì)鄰近管線的保護(hù)措施。工程實(shí)踐表明,文章提出的控制措施合理有效。
[Abstract]:In the construction of urban subway tunnel, it is one of the difficult points to ensure the safety of adjacent pipelines. Taking the Tonghu section of Xi'an Metro Line No. 3 as the research background and using FLAC numerical simulation, the influence of underground tunnel excavation on the deformation of adjacent underground pipelines parallel to and perpendicular to the axis of the tunnel is obtained. This paper predicts the deformation trend of the pipeline after the construction of underground crack through the ground, and puts forward the technical measures of passing through f4 ground crack under the subway tunnel, as well as the protection measures for the adjacent pipelines in the underground excavation construction. Engineering practice shows that the proposed control measures are reasonable and effective.
