摘要
介绍了安(康)—紫(阳)高速公路地质灾害危险性评估方法,采用以环境地质条件背景定性、以工程沿线地质灾害种类、灾害点平均密度、灾害分布长度比例等三个量化指标,结合预测评估确定的危险程度,定性与定量相结合确定拟建工程沿线地质灾害危险性等级,并以此提出防治措施和建议。
Introduced evaluation methods of geological hazard along Ankang-Ziyang freeway, qualitative analysis was determined by background of environmental geology. The number of geological hazard category, average density of geological hazard point and distribution length of the geological hazard were chosen as quantitative index, combined with the results of present and predictive estimation to define the degree of hazard, geological hazard bank was divided by qualitative and quantitative analysis of the planned project, and put forward measures of prevention and cure and suggestions.
