摘要
本文以本溪观音阁水库输水隧道围岩地质条件为基础,根据原有的1/20万区域地质调查报告及1/50万辽宁省区域地质志的资料,通过野外工作,利用先进的遥感技术分析断层的存在和特征,进而研究围岩的稳定性。本文利用弹性力学理论和有限元法,建立二维分析模型,对本溪观音阁水库输水隧道的稳定性进行了定量分析。分析结果表明:围岩稳定性差,隧道开挖时需要制定很多支护和加固方案。
Based on the geological conditions of wall rock in Benxi Guanyinge tunnel, according to the intrinsic investigation report of 1/20 ten thousand areal geology investigation and 1/50 Liaoning areal geology records,by fieldwork and using advanced remote sensing technique analyze the existence and characteristic of the fault to study the wallrock stability .The text use the elastomechanics and the finit element method to build two-dimension analyze model and quantitative analyze the wallrock stability on transport water tunnel. The result shows that the wallrock stability is bad, so it need to make many support and reinforce plan.
