摘要:
地铁盾构法施工会引起临近建筑物的地表沉降,合理地确定其影响范围可为建筑物的检测加固提供理论依据。文章以济南市R2线、M3线沿线地质盾构隧道穿越某既有框架结构为工程背景,采用ANSYS软件对盾构隧道施工引起的临近地表建筑物沉降进行了数值分析。结果表明:2种埋深条件下,建筑物远、近隧端2侧相邻柱基间的地表的沉降差均随着2条隧道中心线与建筑物中心线水平距离的增加呈现出先增大后减小的趋势;当隧道埋深一定时,大净距及小净距条件下分别对应的地表沉降影响范围和相邻柱基间的地表沉降差显著;济南市R2线及M3线盾构法开挖过程扰动影响范围的经验公式及极限值与数值模拟得出的影响范围值基本吻合。
Abstract:
Metro shield construction will cause ground settlement of adjacent buildings, and determining its influence scope reasonably can provide theoretical basis for the detection and reinforcement of buildings. This paper takes the shield tunneling of R2 and M3 lines crossing an existing frame structure in Jinan as engineering background and makes ANSYS numerical analysis of adjacent buildings ground settlement caused by shield tunneling construction. The results show that Under two kinds of buried depth conditions, ground settlement difference between adjacent pillarsat the far and near end of a building increases first and then decreases with the increase of the horizontal distance between the center line of the tunnel and building. When the depth of tunnel is fixed, under the condition of large and small net distance, the influence range of ground settlement and the difference of ground settlement between adjacent pillars are significant. The empirical formulas and limit values of the disturbance influence range of the shield tunneling on the R2 and M3 lines in Jinan City are basically in agreement with the numerical simulation results.
