本文研究了岷江上游地区较场—茂县—汶川长约 10 0km河段上形成多级、多期大型滑坡堵江事件。研究表明 ,这类特殊的地质灾害有其发生发展的特殊的地质背景 ,它们造成的灾害和环境效应较一般的滑坡灾害更严重。有针对性地对岷江上游这类灾害进一步深入研究是很必要的。
This paper studies the multi-stage and multi-stage large-scale landslide plugging events in the upper reaches of the Minjiang River over the length of about 10 km from Maochang-Wenchuan. The research shows that this kind of special geological disaster has its special geological background, which causes more serious disaster and environmental effects than the common landslide disaster. It is necessary to conduct further research on such disasters in the upper reaches of the Minjiang River in a targeted manner.
