摘要
公路隧道的施工过程经常会碰到地质灾害 ,结合云南元磨高速公路在建特长隧道———大风垭口隧道中出现的洞口滑坡、涌水、塌方、突泥等问题 ,多角度论述了产生的因素以及应对措施 ,希望能为今后在类似地质条件下 ,公路隧道的勘查、设计以及施工提供借鉴和帮助。
The investigation of the over-length tunnel---Dafengyakou tunnel at Yuan-Mo expressway in Yunnan province shows that the geological hazards during the construction include water-gushing, collapse, landslide and mud-piping. By multiaspect genetic analysis of causes and corresponding countermeasures, references and support are available for survey, design and construction of sequent road tunnels in the similar geological conditions.
