【摘要】 采用有限元软件ABAQUS建立三维土质边坡模型,基于强度折减法研究了边坡稳定性与坡转角的关系,以及坡转角对边坡稳定性与坡高、坡角和边坡长度关系的影响。结果表明,边坡安全系数随着坡转角的增大会逐渐降低;坡转角对边坡安全系数与坡高、坡角关系的影响较小,但对于边坡安全系数与边坡长度关系的影响较大,且当坡角较大时,坡转角对安全系数与边坡长度的关系的影响就较小;当坡角较小时,坡转角对安全系数与边坡长度的关系的影响就较大。更多还原

【Abstract】 In this paper, the finite element software is used to establish three-dimensional soil slope models. The strength reduction method is used to analyze the relationship between the slope safety factor and the slope rotation angles. The influence of the slope rotation angles on the slope safety factors and the relationship between slope heights, slope angles and slope lengths are investigated. The results show that the slope safety factor gradually decrease with the increase of the rotation angles; the slope rotation angles have little effects on the relationship between slope safety factors and slope heights and slope angles, but the slope rotation angles have an obvious effect on the relationship between the slope safety factors and the slope lengths. When the slope angle is large, the slope rotation angles have little effects on the relationship between the safety factors and slope lengths. When the slope angles are small, the slope rotation angles have an obvious influence on the relationship between the safety factors and slope lengths.更多还原
