摘要
受热带低压、低压槽和冷空气共同影响,2009年10月22日海南岛出现强降水天气过程,东线高速公路发生多处滑坡地质灾害。通过对滑坡成因进行分析,表明东线高速公路发生多处滑坡是在特定地形条件、大风和暴雨等气象因素共同作用下滑动失稳的滑坡。其中热带低压产生的强降水和大风力,是诱发东线高速公路暴雨型滑坡的直接原因。
Due to the common influence of tropical depression,the low pressure trough and the cold air,the strong precipitation synoptic process occurred in Hainan Island on October 22,2009.It caused that the landslide geological disaster happened in several spots in the eastern line highway.By analyzing on the generation reason of landslide,it gained that the landslide which happened in several spots in the eastern line highway was caused by the common effect of special topographical condition,strong wind and rainstorm.The strong precipitation and strong wind which were generated by the tropical depression were the direct reasons which induced the rainstorm type landslide in the eastern line highway.
