摘要
本文结合云南昆楚高速公路隧道施工实际,从开挖、支护等方面考虑,论述在粉质黏土、泥岩地质条件下组织大断面隧道进洞施工时,控制沉降所采用的措施,以保证隧道安全施工,为今后同类围岩隧道进洞施工积累了经验。
Based on the actual tunnel construction practice of Kunchu Expressway in Yunnan,this paper discusses the measures to control the settlement when organizing the large section tunnel construction under the geological conditions of silty clay and mudstone from the aspects of excavation and support,so as to ensure the safe construction of the tunnel and accumulate experience for the tunnel construction of the same kind of surrounding rock in the future.
