摘要
由于山区地形复杂多变,线路展线困难,洞口浅埋偏压、冲沟、降水等不利因素制约着高速公路隧道进洞施工。隧道进洞施工安全和洞口稳定是隧道安全施工的有利保障。结合株岭隧道右线进口工程现场地质条件,研究制定了明挖暗进和盖挖施工相结合的施工方案,确保了隧道安全施工。
With the complexity of mountainous landform and the difficulty in route selection,tunnel entrance construction is restricted by shallow depth,unsymmetrical loading,gully and rainfall,etc.The tunnel entrance construction is important to tunnel safety and stability.Based on geological conditions of ZhuLing tunnel,the author studies and establishes the tunnel entrance construction method for open cutting and covered excavation.
