岩溶山区隧道工程施工引起突水特征及灾害综述

Summaarize on Disaster and Characters of Water Inflow Behavior During Constructing Tunnels in Karst Mountainous Areas

在既有研究成果的基础之上进行了总结分析,就岩溶山区隧道工程施工引起的岩溶突水的类型进行了详细划分。然后重点分析了岩溶突水的基本特征、补给特征、不同填充介质特征以及不同施工阶段特征。最后,根据不同的灾害后果提出了岩溶突水灾害的分级标准,为防治关键技术的研究提供重要依据。

Based on study results in published articles,types of water inflow behavior of surrounding rock were analyzed on detail due to constructing tunnels in karst moutain areas.Then this paper mainly studied basic characters of water inflow behavior,and other characters including water supply,different soils and different constuction steps.Finally,according to different ponderances of karst disaster,a method for disaster classifications was put forward.These results would be considered as important basis for the study on the key prevention technologies.
