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出现洞口滑坡。文章以某一连拱隧道的洞口为例,从地质因素,水的作用以及人为因素三个方面分析了滑坡产生的机制。并提出了相应的加固治理方案,为今后类似工程提供参考与借鉴。 Affected by the engineering geological conditions, hydrogeological conditions and human factors, it is easy for the tunnel tunnel landslide to occur during construction. Taking a tunnel in a multi-arch tunnel as an example, this paper analyzes the mechanism of landslide occurrence from three aspects: geological factors, water effects and human factors. And put forward the corresponding reinforcement management plan for future similar projects to provide reference and reference.
