海南省特殊地质条件对山岭隧道施工的影响研究

Study on the Impact of Special Geological Conditions in Hainan Province on Mountain Tunnel Construction

文中以海南岛作为研究区域,收集海南岛的特殊地质和主要不良地质的相关资料,然后结合山岭隧道的施工特点,筛选对山岭隧道施工影响较大的特殊的地质条件,如滑坡、崩塌、泥石流、和土地沙化、断层破碎带、高压富水带、高地热等。分析上述特殊地质条件对隧道施工造成的要主要影响和安全隐患,对可能出现的地质灾害的严重程度、灾害类型及性质进行预测,最后从施工技术角度提出隧道施工时特殊地质灾害的防治路线。

The geological conditions in Hainan province are complex and special, including landslide,mud-rock flow,desertification of land,shattered fault zone and high pressure zone with rich water,etc. Relevant information on the geological conditions in Hainan province are collected and analysed to figure out the main impact of geological conditions on mountain tunnel construction and the potential safety hazard. The degree,type and quality of potential geological disasters are predicted and control methods of special geological disasters as tunnels are constructed are put forward in terms of construction technology.
