摘要
海西环岛高铁颜春岭隧道富水浅埋,隧道全为V级围岩。隧道洞身穿越古火山口膨胀土火山灰挤压变形严重,围岩遇水软化成泥状,本文就膨胀火山灰富水变形段施工技术作以阐述供类似工程参考。
The water-rich shallow of Yanchunling tunnel of the rotary island high-speed rail in Haixi is V grade surrounding rock. The tunnel body passes through the ancient crater of expansive soil, and the deformation of the volcanic ash is serious. This paper expounds the construction technology of the expansive water-rich deformation section of the volcanic ash.
