震后映卧路沿线泥石流发育分布特征及防治措施

Features and control measures of debris flow along the highway from Yingxiu to Wolong,Sichuan province

震后映卧路沿线泥石流发育分布呈面积广、发生频率高等特点。调查结果公路沿线主要发育泥石流两类57条,其中沟谷型泥石流28处,坡面型泥石流29处,沟谷型泥石流以大型—特大型为主,坡面型泥石流以小型为主;针对该区泥石流的发育特征,提出了生物防治和工程治理相结合的防治措施,对映卧路的防灾减灾工程有积极的意义。

Debris flow has a wide distribution and frequent occurrence along Yingwo Road after ＂5.12＂ earthquake, The survey results show that there are 57 debris flow valleys, Among them, 28 debris flow valleys belong to valley debris flow, and 29 debris flow on slope, valley debris flow with large-extra large, and debris flow on slope with small, For the development of the area of debris flow characteristics, a combination of biological control and project management control measures is put forward, it gives a positive to Yingwo Road in disaster prevention and mitigation projects.
