摘要： 公路特大型泥石流是迄今尚未解决的公路病害,遵循公路泥石流防治的特殊性所开发的速流结构、底埋隧道、翼型墩汇流技术及糙桩技术是该类泥石流极其有效的防治技术[1,2].笔者根据这些单体技术构建了4类综合治理模式,即1)拦渣坝+速流结构,2)底埋隧道+速流结构,3)翼型墩汇流结构+底埋隧道,4)糙底群桩+速流结构,对每类综合模式的适用条件及关键技术进行了分析.从1999年以来实施了多个示范工程,显示出极其良好的治理效果,为同类型的特大型公路泥石流治理提供了重要技术借鉴.

Abstract: Hitherto, giant debris flow along Highway is one of disasters along Highway that haven't controlled effectively. According to features of control giant debris flow along Highway, some control techniques that are effective to giant debris flow along Highway such as high-speed drainage structure, submerge tunnel, converge techniques of wing-shaped pier and piles arrangement to counter the debris flow are developed[1,2]. Based on giant debris flow along Highway, the authors establish four general control models using these control techniques in this paper. i.e. the first general control model is composed of block-gravel dam and high-speed structure, the second model is composed of submerge tunnel and high-speed structure, the third model is composed of converge techniques of wing-shaped pier and submerge tunnel, and the forth model is composed of piles arrangement to counter the debris flow and high-speed structure. Further, suitable conditions and key problems every control model is discussed in the paper. Some testing engineering about these general control models are applied since 1999, which display comfortable effect. It is to say that these general control models provided in the paper are suitable for giant debris flow along Highway.

Key words: Western China, giant debris flow along highway, general control model
