摘要 随着山区的开发,由人类活动引起的工程滑坡更为常见。文章论述的滑坡为一人工开挖的五级高边坡,最大边坡高度45.8 m。受自然和人为等不利因素的影响,坡体变形较为严重,尤其是雨季,坡体变形进一步加剧,滑坡后缘已形成深约0.5~1.0 m的错台,目前四级边坡已出现挤压膨胀迹象;同时滑坡体裂缝密布,岩土松动,形成极大的安全隐患。文章对滑坡的工程地质条件、发展变形特征进行初步分析,提出建议性的治理方案。 With the development of mountain areas, engineering landslides caused by human activities are more common.The landslide discussed in this paper is an artificially excavated five-grade high slope with a maximum slope height of 45.8 m.Due to the influence of natural and man-made unfavorable factors, the deformation of the slope is more serious, especially in the rainy season, the deformation of the slope has been further intensified, and a faulting of slab ends with a depth of about 0.5~1.0 m has been formed on the trailing edge of the landslide. At present, the fourth-grade slope has been squeezed and bulged;at the same time, the landslide is densely cracked and the rock and soil is loose, which forms a great hidden danger.This paper makes a preliminary analysis on the engineering geological conditions, development and deformation characteristics of the landslide, and puts forward a suggested treatment scheme.
