【 摘 要 】

Based on the loess structure and topography of northern Shaanxi area, the construction slope model is built. The numerical simulation method is used to analyze the slope stability coefficient under conditions that the self-weight load, slope ratio and the distance from building to slope. The results are analyzed using soil mechanics. The results show that the construction load, slope ratio and d value have influences on the slope stability. The development trend of the slope stability coefficient with the change of the load depends mainly on the value of d. When the d value is less than 15m, the trend is rapid and continues to decrease; when the d value is 20m, the trend of the stability coefficient is gentle, and the stability coefficient increases with the increase of the load. The influential factors of the slope stability coefficient are different in different stages. The larger influential factors in the stage A is the building load, and the larger influential factor in the stage B is the slope ratio.
