ABSTRACT
With the slope of a coal mine industrial square in Shanxi as the engineering background, analysis and evaluation of loess slope foundation soil are carried out and the natural stability of the slope is evaluated based on the stereographic projection theory. Based on this premise, combined with the regional engineering construction experience and the load conditions of the proposed building, the pile type suitable for the pile foundation of this site is mainly a bored pile and a manual dug pile. Then, the feasibility analysis of the sinking pile is carried out, and many problems should be paid attention to in the design and construction of the pile foundation, as well as the possible engineering risks caused by geological conditions are put forward. Thus, the stability of the whole site slope and the safety of the proposed project are guaranteed. The results can provide a reference for the control design of the loess slope in coal mine areas.
