广西柳州经合山至南宁高速公路吾排隧道工程地质特性评价

Evaluation of engineering geological characteristics of Wucai tunnel from Liuheshan to Nanning expressway in Liuzhou,Guangxi

工程地质特性会直接影响工程设计和施工。文章在详细分析吾排隧道工程地质概况、不良地质作用,水文地质特征等基础上,对隧道岩体工程地质特征、隧道围岩分级进行研究,最后对隧址区域稳定性,隧道进出洞口边坡、仰坡稳定性,隧道围岩稳定性、岩爆及偏压问题进行评价。研究结果为全面提升隧道工程施工质量和建设水平提供可靠的数据支撑。

Engineering geological characteristics will directly affect engineering design and construction. Based on the detailed analysis of the engineering geological overview,unfavorable geological function and hydrogeological characteristics of the tunnel,the paper studies the engineering geological characteristics of the tunnel rock mass and the surrounding rock classification of the tunnel. Finally,the stability of the tunnel area and the tunnel entrance and exit. The slope,stability of the slope,stability of the surrounding rock of the tunnel,rockburst and bias are evaluated. The research results provide reliable data support for comprehensively improving the construction quality and construction level of tunnel engineering.
