研究发现 ,高速滑坡运动到谷底时 ,多数会与对岸岸坡发生碰撞 ,使滑体前部及对岸受撞岩体表部碎裂 ,形成滑坡碰撞构造。由于强烈的碰撞作用 ,滑体内部块体之间嵌合紧密。河流下切后 ,破碎但嵌合紧密的碰撞体卸荷松动 ,岸坡稳定性随之降低。由此提出滑坡碰撞模式、碰撞构造成分 ,并对其岸坡环境效应进行了探讨。
It is found that when the high-speed landslide moves to the valley bottom, most of the landslide collide with the opposite bank slope, causing the front part of the slide body and the opposite surface of the impacted rock body to fragment and form the landslide collision structure. Due to the strong collision, the blocks between the slide bodies are tightly fitted. After undercutting the river, the crushed but closely fitted collision body unloads loosely and the stability of the bank decreases. Based on this, the landslide collision mode and collision structure components are proposed, and the environmental effects of the bank slope are discussed.
