摘　　要：介绍了基于结构单元的边坡抗滑桩加固模拟方法,比较了结构单元模拟计算结果与实体单元计算结果,并以乱石岗边坡抗滑桩设计为例,通过改变抗滑桩的桩长、截面尺寸和桩间距分析了设计参数对边坡加固效应及抗滑桩剪力和弯矩的影响规律。结果表明,结构单元模拟抗滑桩简单、实用,为抗滑桩优化设计提供了科学依据。The slope anti-slide pile reinforcement simulation method based on structure elements is introduced in this paper.The simulation results with structure elements are compared with that by solid elements.Taking the design of Luanshigang slope anti-slide pile for an example,the influence of design parameters on slope reinforcement,shear force and bending moment are analyzed by changing the pile length,sectional dimension and distance of piles.The results show that the proposed method is simple and practical,which provides scientific basis for optimization design of anti-slide piles.
