摘要
浅埋偏压隧道施工中易出现山体开裂、滑坡等病害,影响高速公路的安全性。基于天大高速公路黑石崖隧道山体开裂下滑的工程情况,全面分析各类地质因素后,提出了合理的处治方案,确保边坡稳定,对同类工程处治具有一定的参考价值。
Diseases like crack of mountain massif, landslide are easily appeared in the construction of shallow - buried bias tunnel, which may influence the safety of expressway. Based on the project condition of crack and slide of mountain massif of Heishiya tunnel of Tianda Expressway, reasonable treatment schemes are put forward after comprehensively analyzing all kinds of geological factors, so as to ensure the stability of side slope and provide certain reference value for the treatment of similar project.
