浅析页岩气地段隧道施工风险识别及评估——以湘西地区地质情况为例

An Analysis of Risk Identification and Assessment of Tunnel Construction in Shale Gas Area---A Case Study of Geological Setting in Xiangxi Region

本文以页岩气地段的地质情况为出发点，分析了南方扬子地区下寒武页岩，识别出了一些在页岩地区隧道施工的风险因素，对这些因素进行了等级评估，为在页岩气地段隧道施工提供一些参考。

Based on the geological conditions of shale gas, this paper analyzes the lower Cambrian shale in Southern Yangtze area, identifies the risk factors for tunnel construction in shale region and evaluates the level of these fac- tors, which can provide some references for the construction of the shale gas tunnel.
