摘要
受工程地质条件、水文地质条件及人为因素等的影响,公路隧道洞口施工过程中易发生洞口滑坡。综合连霍国道主干线宝鸡天水高速公路码头隧道洞口滑坡的形成特点、工程地质及水文地质特征,通过计算对该洞口滑坡稳定性进行分析,提出了相应的加固治理措施,为今后类似工程提供参考与借鉴。
Landslides easily occur at the tunnel portal during construction due to the engineering geological condition,hydrogeological condition and some human activities.Taking into account the landslide formation feature,the geological condition as well as hydrogeological condition of Matou tunnel of Baoji-Tianshui Expressway,the landslide of tunnel portal is analyzed.The sliding surface position is decided.Finally,the reinforcement scheme is proposed.This study can provide reference for similar engineering.
