公路隧道施工中的地质灾害及相应措施的分析

Analysis of Geological Hazards During Road Tunnel Construction and Corresponding Countermeasures

公路隧道的施工过程经常会碰到地质灾害 ,针对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。

Based on the investigation of the super long tunnel Dafengyakou Tunnel at Yuan Mo Expressway in Yunnan Province, this paper presents the geological hazards occurred during the construction, including water gushing, collapse, landslide and mud piping. By multi aspect analysis and representation of corresponding construction measures, this paper provides a reference for surveys, designs and construction of road tunnel in similar geological conditions.
