【摘要】 本文以有限元分析为手段,通过控制深基坑开挖的土层内力释放调解,来模拟地层及结构变形随施工阶段变化的特点,从而分析基坑围护体的变位、坑底隆起量及其对邻近地铁站沉降及水平位移的影响,从而希望对基坑开挖施工、监测任务起到一定的指导作用。更多还原

【Abstract】 Finite element analysis method was used in this article,internal force of soil layer was controlled to simulate the distortion of groundwork and structure in every construction phases,and the horizontal displacement of excavation supporting,the vertical displacement of excavation bottom,and the influence on sedimentation and hori- zontal displacement of adjacent subway station was analyzed accordingly.The analysis result will be helpful in the following construction and monitor of deep excavation.更多还原
