| 摘 要： | 塌方一直是我国隧道建设领域研究的热点问题。从施工过程中冒顶塌方形成经过、产生塌方原因入手,对渝湘高速公路正阳隧道一次塌方事故提出治理方案,认为岩隙渗水作用于覆盖层较薄、渗透性强的松散破碎地段使隧道上方岩土体的自稳能力恶化;通过坍口设置截水沟及多种形式注浆技术,及时加固坍塌体,封堵岩隙渗水。方案效果良好,具有一定借鉴意义。

| Abstract: | Tunnel collapse has been a key issue in the tunnel construction field in China.A treatment method was formed for a collapse in Zhengyang Tunnel of Yuxiang highway based on the formation process of roof fall and the cause of collapsing accident in the construction.Self-stability of the surrounding rock above the tunnel is exacerbated by the affection of the thin overburden layer and weak stratum of rock with the groundwater in cranny.A channel is constructed around the mouth of collapse to strengthen the collapsing section and succeeded to seal the seepage water. |
