摘要
根据塑性极限分析理论,考虑格栅的加筋效应,对土工格栅均布加筋土坡的稳定性进行了上限解法;由此,确定了格栅加筋土坡临界高度的上限和稳定数。井与无加筋情况下边坡的计算结果进行了对比分析;通过变动参数,计算分析了格栅加筋土坡坡角、表面坡角、土的内摩擦角及格栅抗拉强度对加筋土坡临界稳定数的影响。
Based on fundamental theory of limit analysis of plasticity, the upper bound procedure is employed in limit analyzing the stability of soil slope reinforced by uniformly distributed geogrid. It obtains expression of the upper bound of critical height and stability number for reinforced soil slope, which are compared with non- reinforced soil slope. Eventually, the effects of slope angle, surface inclination angle, frictional angle of soil and geogrid tensile strength on stability number are analyzed for retaining soil slope.
