基于河南省道S250线灵宝—朱阳段改建工程的地质灾害特征研究

Features of geological hazards along reconstruction project of Lingbao—Zhuyang Section of Henan Highway S250

对省道S250线灵宝—朱阳段改建工程沿线地质灾害进行了调查。结果表明:沿途地质灾害较发育,识别出崩滑、滑坡和不稳定斜坡9处,在暴雨及地震作用下极易产生滑坡或崩塌;沿途地质灾害危害程度均为较严重,危险性为小-中等,严重威胁着S250省道公路、货运、客运车辆、行人、游客及窄口水库大坝等的安全。本文的研究成果可为进一步编制治理方案提供基础依据。

The geological hazards along the reconstruction project of Lingbao—Zhuyang section of provincial highway S250 were investigated.The results showed that the geological hazards along the road were relatively developed,in which 9 sites of landslides and unstable slopes that were easy to produce landslides or collapses under the action of rainstorms and earthquakes were recognized.The geological hazards along the road were relatively serious,and the risk was small-medium,which seriously threatened the safety of S250 provincial highway,freight,passenger vehicles,pedestrians,tourists and narrow-mouth reservoir dams.The research results of this paper provided a basis for further compilation of governance programs.
