摘要
特殊的地理位置,复杂的地质构造,丰富的松散固体物质,陡峭的地形加上降水集中的气候,为泥石流的发生创造了客观条件。西藏浪卡子-洛扎公路沿线的泥石流多为山坡、粘性、稀性或过渡型泥石流,其危害主要是淤埋公路。结合当地的环境和公路的等级,主要采用过水路面、涵洞等疏排措施进行治理。
Special geography setting, complex geology structure, abundant loose materials, steep landform and frequent precipitation are the necessary conditions for debris flow occurring. The debris flow along the Langkazi-Luozha road in Tibet is inhillside, mud and stone, transition or watery debris flow. The debris flow can fill up and bury road, which threaten the road seriously. According to the circumstance and the grade of the road, the methods to deal with them are setting watercrossing road surface and （or） culvert along the Lang Kazhi-Luoza road.
