【摘要】 基于随机介质理论,考虑了隧道直径、埋深、土体削减、围岩性质等因素对主要影响角和间隙参数的影响,研究了Park位移模式3对盾构掘进引发的隧道轴线上方任一土层深度的空间变形。工程算例结果表明,本文方法相对于经验解其曲线变化趋势更符合实测值,相对于已有的研究结果其计算数值偏大,故工程应用偏于安全。更多还原

【Abstract】 Based on the stochastic medium theory,the spatial displacement of the deep soil is drawn in terms of the Park third displacement mode by considering the series parameters,such as the tunnel diameter, the tunnel buried depth,the ground loss,the properties around the rock,the ground influence angle,gap parameter,and so on.Combining with the specific engineering example and the existing research results,it is proved that the study curve trend of this paper is more in line with the measured field dates and the dates are bigger,so the results are more safe for the engineering application.更多还原
