| 摘 要： | 本文通过山洪及泥石流灾害实例调查,分析了山洪及泥石流灾害的特性,总结了从降雨到灾害形成的5种途径:(1)集中暴雨诱发滑坡体的高速滑动,滑坡体堵塞溪流形成溃决泥石流;(2)集中暴雨诱发陡坡崩塌,崩塌土流动化形成泥石流;(3)溪流河床累积性淤积,水位抬高山洪漫溢;(4)长历时暴雨形成山洪,两岸崩塌后退;(5)人为弃渣或前期松散堆积物在暴雨过程中形成泥石流。由于山洪灾害形成过程不同,成灾范围及其严重性相差较大,必须采取与之对应的防治措施,才能达到预期的效果。

| Abstract: | Based on investigation of actual torrential flood disasters, the authors analyzed the characteristics of torrential flood disasters.The formation processes of torrential flood disasters can be classified as follows:(1) sliding bodies due to concentrated rainstorm clog brooks and induce debris flow; (2)colluvial soil due to concentrated rainstorm flow forms debris flows;(3) stream bed has been cumulatively deposited and torrential flood flows over banks;(4) longtime rainstorm scour banks and induce bank collapse; (5) previously manmade loose deposit and dump form debris flow during rainstorm.The authors put forward some preventive measures against different types of torrential flood disasters.- |
