介绍了京沪高速铁路(江苏段)沿线的地质环境条件,总结了沿线的地质灾害类型,将地质灾害的危险性划分为渐进式和突发式,并将地质灾害发生的可能性与其危险性分别予以量化,应用综合指数方法定量地评价了京沪高速铁路(江苏段)的地质灾害危险性大小。结果表明,综合指数评价方法的评价结果要比定性评价更精确,对于线路的勘察、设计以及地质灾害防治等,更具有指导意义。
The geological and environmental conditions along the Beijing-Shanghai high-speed railway (Jiangsu section) are introduced. The types of geological disasters along the route are summarized. The risk of geological disasters is divided into gradual and sudden type. The possibility of geological disasters and its danger Respectively, to quantify the risk of geological disasters of the Beijing-Shanghai high-speed railway (Jiangsu section) quantitatively by the method of composite index. The results show that the comprehensive index evaluation method is more accurate than the qualitative evaluation, which is more instructive for the investigation and design of the lines and the prevention and control of geological disasters.
