摘要
通过对近几年台风暴雨引发公路水毁相关资料收集和整理,分析气象、工程地质背景条件,总结了我国东南地区台风暴雨引发公路水毁灾害的成因条件。台风暴雨过程的气象特点、地形地貌条件及山区公路建设特点等外因与内因的综合叠加,相互作用,水毁灾害也就自然发生;并划分水毁发育阶段,研究各个阶段成灾机理过程的作用程度。提出切实有效的防灾对策,为公路职能部门的相关决策提供科学依据。
The causations of typhoon-rainstorm-induced highway flood hazard were summed up by collecting and settling correlative datas in recent years and analyzing meteorological,engineering geological background condition.Within intergrated superposition and reciprocity between external and internal causes,such as the meteorological characteristic of typhoon rainstorm process,the landform-physiognomy conditions and the construction-features of mountain roads,highway flood hazard can easily happen.Then,the development stages of flood hazard were classified,and the effect degree of disaster mechanism process at all stages were studied.In end of the paper,practical and effective control measures are presented,to afford scientific basis while relevant functional departments in decision-making.
