摘要
黄土分布区由于人为削坡、振动、降水或融雪引发滑坡,造成人员伤亡和经济损失。通过现场调查,分析霍城县黄土滑坡发育特征及诱发因素,斜坡为易滑的第四系黄土状粉土,主要发育坡度13°~40°,以及大于30°斜坡上,滑坡类型为崩滑,运动速度快,滑体坡降完全脱离滑床,且以浅层、表层滑坡为主;滑坡多分布于黄土山坡阴坡处,在1000~1800 m低山丘陵-低山区以第四系松散堆积物为主,并受人类工程活动影响易于发生。
In loess areas,landslides caused by man-made slope cutting,vibration,precipitation or snow melting have caused casualties and economic losses.This paper analyzes the development characteristics and inducing factors of loess landslides in Huocheng County through on-site investigation.The slopes are quaternary loess-like silt soils that are easy to slip.The slopes are mainly developed on slopes of 13°~40°and>30°.The type of landslides is avalanches and landslides.The movement speed is fast,the landslide slope is completely separated from the slide bed,and is mainly shallow and surface landslides;landslides are mostly distributed on the shady slopes of loess hillsides,and loose deposits of the Quaternary system in the low hills of 1000~1800 m.Mainly and prone to occur under the influence of human engineering activities.
