摘　　要：本文运用极限平衡理论分析砂土抗剪指标的变化规律。通过对大量的勘察资料的分析,找出了区域性离石黄土的内磨擦角变化特点。分析表明对于赵庄矿区的Q2黄土,存在着滑坡危险,在地下水或地表水作用下,土层的饱和度由75%上升到饱和状态时,土层的内摩擦角减小0.5倍。提出了针对离石黄土滑坡的治理方案。This article utilizes the limit equilibrium theoretical analysis the change rule of sandy soil anti-to cut index.Through the massive reconnaissance material's analysis, the regional loess away from stone internal friction angle's variation characteristic had been discovered. The analysis indicated that the Zhao village mining area's Q2 loess has the landslide danger. With the ground water or the surface water function, the soil layer degree of saturation by 75% rise to the saturated condition, the soil layer internal friction angle reduces 0.5 time. The remediation plans and considerations had been raised to the loess away from stone in a landslide.
