摘　　要：绕行(避让)或穿越是道路面对泥石流灾区两种传统的处理方式。绕行就是远离灾区,穿越有从流通区或从堆积淤埋区通过两种模式。在淤埋区通过包括地上桥梁(忌用涵洞)和地下隧道两种模式。地上模式中还有从扇顶、扇腰或扇缘通过三种模式可供选择。这些原则与模式均与泥石流性质、规模和公路级别息息相关。本文对这些模式进行了对比研究,最后提出了道路泥石流工程防治的原则与模式。There are two principles for constructing roads in potential debris flow hazards areas, one is bypassing, the other is traversing. The former means constructing roads far away from the hazards areas; the later includes two modes, one of the choices is building roads pass through currency region, and another is pass through the deposition region. Otherwise, building bridge and underground tunnel will be the two kinds of patterns to get across the deposition region. However, culvert is prohibitive in this region. In addition, three patterns are provided to transit deposition region, passing the top area of deposition fan, the middle area, and the edge area. All of the modes are related to debris flow characters, magnitude and roads level. Based on research and discussion, this paper presents engineering modes for prevention and control mountainous roads debris flows.
