针对黄土区储煤仓高边坡回填土稳定性较差的情况，利用非限性有限元法建立加筋边坡稳定性计算模型，分析高边坡加筋土土体强度、坡背面板及筋带空间位置与安全系数的关系。结果表明，对高边坡回填土进行加筋带加固显著增大了边坡的承载能力和安全系数；土体强度（土体摩擦角和黏聚力）增加，边坡稳定性明显增大；加筋层数增加边坡的稳定性增大，但存在适当范围；坡背面板的加入增加了边坡的稳定性，但工程造价也随之增加。该研究为高边坡加筋土的有效利用提供了参考。

Aimed at eliminating the less stable backfill in high slope of coal storage bunker in loess area, this paper introduces the development of the stability calculation model of reinforced soil slopes by using nonlinear finite element method and the analysis of the relationship of soil strength by high slope re- inforced soil, back slope, the space position of reinforced band and the safety factor. The results show that the reinforced bands leads to significant increases in the bearing capacity and the safety factor of slope, definite increases in soil strength ( soil friction angle and cohesive force) , and remarkable increase in slope stability. The increasing stability of the slope results from the increasing reinforced layers, but with appropriate range and the greater slope stability due to adding back slope concrete panel is offset by a increasing the project cost. The study could provide a reference for the effective use of the high slope reinforced earth.
