摘要
作者曾在1989年提出关于高速滑坡形成机制的一种解释———“闸门效应说”,此后,又进行了这方面的模型试验,并在滑坡预报研究中监测到焦家村滑坡的变形过程,二者均证明“闸门效应说”是正确的,本文对此做了简要介绍。本文还据实际观察到的现象指出,由于环境条件不同,高速滑坡滑体的运动既可以表现出滑动特征,也可以很快转化成碎屑流表现出流动特征。
he presumption of sluice valve was proposed by the present author as a kind of explanation for the formation mechanism of high speed landslides in 1989. After that, the author and his co workers carried out some modeling tests in this area, and obtained the deformation procedure of Jiaojia Village Landslide, a case study for predicting the failure time of slope. Both of them shown that the presumption of sluice valve is reasonable and believable, which was introduced in this paper. Moreover, according to the macro traces from field investigation, the present author pointed out that the movement of a rapid landslide could represent the sliding character or change into a debris flow to show the flowing features.
