摘要:
2009-07-31,四川省凉山彝族自治州西溪河流域金阳县地洛电站施工区暴发泥石流,造成9人死亡、施工道路及设施损毁。通过现场调查和分析认为,"7.31"泥石流是一场高容重低粘度坡面型泥石质泥石流,强降雨是此次泥石流形成的激发条件,工程弃渣是其形成的物质基础和条件,过沟公路未合理设置排水涵洞,路基被毁,沿途大量物质补给是泥石流形成的促进因素。"7.31"泥石流隐蔽性强,人们对其危害范围认识不足,防灾意识薄弱,监测预警不到位,是造成人员伤亡与财产损失的重要因素。结合西溪河流域水电开发的现状,针对性地提出了规范人类工程活动,提高防灾意识,加强地质灾害的监测预警等防治对策,建议进一步加强中小水电工程...
