摘要
分析了隧道洞口段塌方发生的成因,同时对锚喷网加固、小导管注浆等处治技术进行了探讨。结合公路隧道洞口塌方处理实践,论证了处治措施的可行性,对相关工程有一定的借鉴作用。
This paper analyses the causes of tunnel portal collapse occurrence. At the same time the reinforcement technology of shotcrete and small duct grouting are discussed. According to the practical treatment of tunnel portal collapse, the feasibility of measures are demonstrated which has a certain reference for related engineering.
