摘要
根据省道303线南华特长隧道洞口段复杂地质条件,通过介绍洞口坡面防护、抗滑桩桩基挡墙、套拱加长、开挖工法、超前预支护及初期支护加强等施工关键技术以及发生变形后的加固处治措施,解决了隧道进洞时穿越堆积体技术难题[1],为类似工程施工及优化设计提供借鉴。
According to the provincial highway 303 south China long tunnel entrance section of complex geological conditions,by introducing the mouth of the slope surface protection,anti-slide pile retaining wall,set of arch length,primary support,excavation method,the preliminary support of the advanced and strengthen the construction of the key technologies such as and after deformation reinforcement processing measures,deposit through the technical problem solved the tunnel into the hole,serve as a reference for similar engineering construction and the optimization design.
