| 摘 要： | 隧道开挖过程中,地下水渗流作用对围岩的稳定性存在较大影响。针对洛阳至栾川高速公路高崖头隧道的具体情况,采取有限差分软件FLAC3D,建立三维模型,研究了考虑渗流作用和不考虑渗流作用情况下围岩的位移值,并与现场监测值进行对比验证,进而利用数值模拟的结果分析了隧道围岩的稳定性。研究结果表明:在考虑渗流作用下拱顶下沉和周边位移均大于不考虑渗流作用的情况,与现场监测值更为接近,隧道围岩处于稳定状态,研究结果对施工实践有一定的指导作用。

| Abstract: | In the process of tunnel excavation,the groundwater seepage has greater impact on the stability of wall rock.According to the circumstances of the high cliff tunnel in highway from Luoyang to Luanchuan,the paper applied the finite difference software FLAC3D,established the three-dimensional model,researched the displacement of wall rock when considered the seepage or not considered the seepage,and compared with the value of field monitoring data.Analyzed the stability of surrounding wall rock by using the r... |
