摘要
在地质勘查的基础上,研究姜家沟泥石流成灾条件、机理、规模及基本特征。对多种地质条件的综合量化分析,得出其现处于中等易发状态。为减弱泥石流活动和减轻灾害损失,提出以工程措施为主、减少泥石流物源、加强监测、及时警报的对策。
studied for Based on the debris their present state of ening monitoring and the geological investigations, formation conditions, formation mechanism, size and characteristics are flows in Beichuan. The comprehensive quantitative analysis of a variety of geological conditions concludes medium-proneness. It is proposed to use constructions mainly, while reducing material sources, strength- offering timely warning, to control.
