摘要:
甘肃省舟曲县城2010年"8.8"特大泥石流灾害损失惨重,造成1 675人死亡失踪,损毁房屋200余栋,世界震惊。通过现场对舟曲三眼峪泥石流调查和研究,认为"8.8"特大泥石流灾害既是天灾(自然条件),又是人祸(人为因素)。换言之,自然条件和人为因素是导致"8.8"特大泥石流的主要致灾因素。自然因素调查结果表明:1.三眼峪流域在25 km2范围内高差达2 500 m,且大眼峪和小眼峪沟谷纵坡降分别达到33%和36%,地形较为陡峻;2.三眼峪流域内松散固体物质总量约为26.4×106m3,被"8.8"特大泥石流冲出的固体物质仅为1.52×106m3,松散物源丰富;3.小时降雨量为77.3 mm,...
