摘要

那昌公路线路大致以东西向展布在藏东南大拐弯的北部，历次构造运动强烈，地震活动频繁，分布有规模不一的滑坡、崩塌、岩屑堆、古冰川和泥石流堆积，这些堆积体因修建公路受到不同程度的削、切和开挖，在地形、河流、降水等条件下，不断发生新的滑坡、崩塌和泥石流危害。与公路有关的主要危害类型有：间歇错落型滑坡和多级牵引式滑坡；雨洪型泥石流，滑坡型泥石流和冰湖溃决型泥石流，这些都极大地危害着公路建设与交通运营。

Abstract

Naqu-Changdu highway line is located in north part of South-eastern Tibet Great Turner with EW direction

a great deal of landslide

collapses and debris flow deposits distribute due to extensive tectonic movements and frequent earthquake activties.All of these deposits are hazardous to reconst ruction and transportation of highway.Some new landslide

collapse

and debris flow disasters are tiggered by unreasonable cutting and digging activities.The main disastertypes in highway is intermitted collapse type landslide

multi-graded pulling type landslide

rainstorm debris flow

landslide type debris flow and glacial lake outbursttype debris flow.
