From the traditional geological methods and numerical simulation quantitative evaluation,taking the Emperor Temple tunnel as an ex-ample,this paper comprehensively analysis and research on tunnel surrounding rock engineering quality,and made finite element numerical simu-lation to geological model,provided certain reference for the stability evaluation of double lines long tunnel surrounding rock.%从传统的地质方法和数值模拟定量评价入手，以天子庙隧道为例，对隧道围岩工程质量进行了综合分级研究，并对地质模型进行了有限元数值模拟计算，为双线长隧道围岩稳定性评价提供了一定的借鉴。
