摘要
为解决在硬质围岩隧道中快速连续施工,对连云港东疏港高速公路后云台山隧道塌方掉块进行全面系统地分析,探讨在硬质围岩隧道中塌方掉块的各种形式,说明控稳结构面的存在是塌方掉块产生的关键因素,并归纳提出控稳结构面预测方法。通过分析可知,利用控稳结构面预测方法配合超前地质预报手段,并采取有效加固围岩等措施能够预防和减少硬质围岩隧道塌方掉块事故的发生。
In order to fulfill rapid and continuous construction of tunnels in hard rock mass,the situations of cave-ins in Houyuntaishan tunnel on harbor highway in Lianyungang is analyzed,the types of cave-ins in tunnels in hard rock mass is discussed and structure plane stability control methods and major causes for the cave-ins are presented.Conclusion is drawn that cave-ins in tunnels in hard rack mass can be predicted and can be minimized by adopting structural plane stability control methods,advance geology forecasting methods and effective rock mass reinforcement.
