摘要
在现场调研、工程地质勘察及隧道监控量测的基础上,研究了十漫高速公路火车岭隧道施工中出现的大变形问题,通过分析该隧道变形破坏特征,从围岩岩性条件、地下水条件及地应力条件等因素对该隧道大变形机制进行了研究,结果表明,大变形为围岩塑性流动及围岩膨胀变形的综合作用。提出了综合治理措施,以确保隧道安全顺利贯通。
Based on field investigation, engineering geological exploration and spot monitoring measurement, the large deformation of Huocheling tunnel on Shiyan-Manchuanguan Highway is studied. By analyzing the features of deformation and failure of the tunnel, the mechanism of large deformation is discussed from the perspectives of surrounding rocks, groundwater and earth stress. It is found that the joint action of plastic flow and swelling of surrounding rocks resulted in the large deformation. Following this, measures are presented to make sure that the tunnel will be operating safely.
