摘要
深入研究、合理控制由隧道开挖引起的地表沉降具有十分重要的实际意义。以武汉地铁虎泉—名都区间隧道开挖工程为背景,运用简化随机介质理论公式,以典型地表沉降和隧道断面收敛监测位移为基础,对区间各典型断面进行位移反分析,得到隧道断面收敛面积△A和tanβ(β为影响角),并总结类似研究区域施工和地层情况的隧道开挖引起地表沉降的计算参数取值,研究结果可为武汉地区后续大规模地铁建设提供参考和依据。
In-depth research and reasonable control of tunnel excavation induced ground subsidence are of great practical significance. Taking the excavation of Huguan--Mingdu section of Wuhan subway as background, based on the typical ground subsidence and monitored displacement of the tunnel cross section convergence, simplified stochastic medium theory formula is used to back analyze the displacement of typical sections. The parameters, convergence area △A and tan β, where β is the influextial angle, are obtained from the calculation. Ranges of key parameters values are given in the similar conditions. Therefore, it has some practical value in guiding the construction of Wuhan subway.
