摘要
塌岸是黑龙江岸边(本文仅指中方沿岸)的主要地质灾害,在2379km长的界河段(包括支流乌苏里江界河段)上,有150处总长566km的江段塌岸灾害,塌岸江段每处长0.25—7.0km,塌岸造成江岸后退速度为2—36m/a,致使我国沿江地区每年都有部分国土资源流失。本文在叙述塌岸灾害的发育特征、分布规律的基础上,着重探讨了塌岸灾害的形成机制,进一步提出了沿岸国土整治措施。
Bank slump is a main geological hazard along the bank of Heilongjiang(the paper only points out the bank within China). Along the boundary section which is 2379 kilometers long (Including its branches-Wusulijiang), there are one hundred and fifty collapse spots with a total length of 566 kilometers. Each spot, bank slump is 0. 25 to 7. 0 kilometers long. The backing speed of river bank is about 2 to 36 meters every year because of bank slump. As the result of river bank collapse, territory resource is reducing every year.
Based on the features of bank slump development and distribution the paper discusses maimly its forming mechanism makes the suggestion of schemes of territory harnessing.
