摘要

长江流域现已研究过的滑坡有1

203处

主要分布在上游西部地区

数量多

规模大;其次是中部地区

规模多为中小型

但涪陵—南津关的长江两岸斜坡部分地区有上千万立方米的大型和特大型滑坡;东部区滑坡分布更少

规模以几万到几十万立方米居多。这是由于新构造活动、岩土体稳定性、斜坡形态、降雨强度、河流侧向侵蚀和人为活动对斜坡变形的影响所致。随着经济和工程活动增多

流城内的滑坡有急剧发展趋势。

Abstract

Up to now

203 landslides have been researched in Yangtze River Valley. Most of them distribute along with the up reaches of Yangtzi River on the western part of this valley in large scale and great number. The others are in the middle part of the valley

the major scales are small to middle

but on the slopes of the two banks of Yangtzi River in the section between Fuling and Nanjunguan

the large and the largest landslides with a purt of volume over thousands cubic meter are distributed. The eastern part is with fewer landslides

its major scales is in 10 to 100 thousands cubic meters. All of those mentioned above is from neotectonic action

stability of rock

shape of slope

rainfall intensity

the side erosion of river and the human activities. As the economy and engineering activity is increasing

the landslide event is tending to develop sharply.
