现有的研究成果主要为水平、近水平、缓斜基底排土场变形破坏模式及防治措施

The existing research results mainly include the deformation failure mode and prevention measures of the horizontal, nearly horizontal, and gently inclined basement dumping sites. There are few studies on the large-incline basement dumping. The <br>literature [] solves the blasting parameters of pockmarked blasting from the blasting point of view. , Did not analyze the deformation and failure mechanism of the <br>dumping site after pit blasting from the perspective of stability. In this paper, combined with the engineering background of the Luzigou anticline dumping, the relationship between the ratio of the base treatment area and the stability coefficient is first studied, and then the treatment difference is calculated. The influence of the region on the stability of the dump site is based on the actual field and numerical simulation to study the deformation law and failure mechanism of the dump site with a large dip angle.

The existing research results are mainly horizontal, near-level, slow-slope substrate deformation destruction mode and prevention measures, for the large inclination base drainage less research,<br>The paper solves the blasting parameters of hemp blasting from the angle of blasting, and does not analyze the deformation and destruction mechanism of the soil field after hemp blasting from the angle of stability.<br>In this paper, combined with the engineering background of the back sloped drainage of the reed ditch, the relationship between the substrate treatment area ratio and the stability coefficient is first studied, and then the effect of dealing with different areas on the stability of the drainage field is calculated, and the deformation law and destruction structure of the large inclination substrate drainage field are studied based on the actual and numerical simulation of the site.
