【摘要】 我国西部地区铁路、公路交通干线共有泥石流灾害 4 70 0余处 ,占全国道路泥石流灾害的 70 %以上。泥石流分布广泛 ,成灾方式多样 ,灾害严重 ,制约了西部地区交通建设的发展。本文提出了做好路线方案比选 ,防患于未然 ,正确评判泥石流沟和发育现状 ,工程设计要适合泥石流特点 ,以及提高防灾减灾勘察设计水平 ,开展泥石流防治试验示范工程研究等六条防治对策。更多还原

【Abstract】 There are more than 4700 debris flow hazards along the main traffic lines of railway and highway in western China, which account for 70 percent of the debris flows along traffic lines in the whole country. Debris flows are distributed extensively, frequently cause serious damage and losses in traffic construction in western China region. A large number of studies and investigations, six measures for controlling debris flows in the paper, which are correctly distinguishing debris flow gullies and their development process strictly choosing suitable route, engineering design in donsideration of the characteristics of debris flow, rising survey and design level for mitigating and preventing disaster,and carrying out debris flow prevention testing and demonstrating works.更多还原
