摘要
随着我国特长公路隧道建设工程不断增多,地质条件趋于复杂,对于隧道掌子面前方地质情况的探测精度提出了更高的要求。本文提出一种随爆地震超前探测方法,正演模拟了隧道开挖过程中常见的不良地质体断层,研究其在随爆条件下波场传播特征。将该方法在芜黄高速公路雾岭头隧道进行工程应用,探测结果与现场情况高度一致,说明该方法的有效性与可行性,可为隧道施工建设提供指导。
With the increasing construction of long highway tunnels in China,the geological conditions tend to be complex,and the detection accuracy of the geological conditions in front of the tunnel face is required to be higher.In this paper,an advanced method is proposed to simulate the common bad geological faults in the process of tunnel excavation,and to study the wave propagation law under the condition of explosion.The method is applied in wuling tou tunnel of Wu Huang expressway,and the detection results are highly consistent with the field situation,indicating the validity and feasibility of the method,which can provide guidance for tunnel construction.
