摘要
总结了二郎山公路隧道岩爆在发生时间、空间、岩性与岩体结构效应等方面的主要特征 ;从改善围岩物理力学性能和应力条件、初期支护加固围岩、二次衬砌诸方面着手 ,阐述了该隧道岩爆的防治措施。
Summarizing main rockburst characters from occuring time and space,quality,structural effect of rockmass in famous Erlang Mountain highway tunnel.In aspects of improving physical and mechanical properties of surrounding rock,stress conditions,reinforcing initial support system and concrete lining etc.,the effective prevention measures against rockburst in this tunnel are elaborated.Some new opinions are also proposed,the construction is controlled.
