摘要
文章以湖北省襄 十高速公路襄樊至武当山段为例 ,提出了建设用地地质灾害危险性评估范围、评估重点的确定方法 ,就地质灾害危险性的涵义展开讨论并给出了明确定义。结合工程实践 ,对现状评估、预测评估与综合评估的要点、方法展开论述 ,提出高速公路地质灾害危险性等级划分标准 ,同时提出以防灾工程投入比大小评估建设用地土地适宜性的量化指标 。
Taking Xingshi express was(Xiangfan to Wudang mountain,Hubei Province)as an example,the paper advances the determination criteria of geological hazard assessment for road construction.Following the comprehensive discussion,a definition on the risk of geological hazard is proposed.Combined with the engineering project,the present and forecasted assessment and risk classification for express\|way geological hazards are presented.Meantime,the quantitative index of invest ratio for hazard prevention engineering in road construction is put forward,finally the countermeasures for existing main problems are suggested.
