摘要
为全面探究隧道洞口深层滑动面形成的机理,提高边坡滑坡处治水平,保证隧道建设及运营安全,文中结合韶惠高速公路施工实践,根据场区内地质、水文及滑动面基本特征,系统分析了隧道口仰坡开裂的具体原因;通过对隧道口边坡稳定性的计算分析,确定了各阶段滑动面的分布范围;提出了针对性处置措施,取得了显著成效。
In order to comprehensively explore the formation mechanism of the deep sliding surface of the tunnel entrance,improve the level of slope landslide treatment and ensure the safety of tunnel construction and operation.Based on the construction practice of Shaohui Expressway and the basic characteristics of geology,hydrology and sliding surface in the field,the paper systematically analyzes the specific reasons for the cracking of the overhead slope of the tunnel entrance.Through the calculation and analysis of the stability of the tunnel slope,the distribution range of the sliding surface at each stage is determined,and the targeted treatment measures are put forward,and remarkable results areobtained.
