摘要
邻近既有桥桩进行基坑开挖会对其产生复杂的力学影响,为保证既有桥桩的绝对安全,需研究基坑开挖对桥桩的影响规律并采取正确的处理措施。运用有限元软件模拟了地铁车站施工对邻近轻轨桥墩的变形影响,并提出在施工中加强围护结构及邻近建(构)筑物的变形监测,确保施工和工程的安全。
Foundation pit excavation will affect the nearby existing bridge piers seriously.In order to ensure the safety of the bridge piers,the effect of excavation on the bridge piers was studied and correct treatment measures were adopted.The finite element software PLAXIS was used to study the influence on adjacent light rail piers,and strengthening the deformation monitoring on enclosure structure and adjacent buildings(structures)during construction was proposed so as to ensure the safety of construction and project.
