摘要:
为了研究采用抗滑桩加固含软弱夹层的坡积土边坡的合理性,以某天然边坡为例,采用有限元法和强度折减法定量分析计算了该边坡采用抗滑桩加固前后的应力应变状态和稳定性大小。计算结果表明:抗滑桩可以有效地遏制潜在滑坡体的进一步变形和塑性区扩展,加固后边坡整体稳定性明显提高,整体垮塌的地质灾害风险得到控制,抗滑桩桩体的受力和变形均在设计允许值范围内,说明抗滑桩设计采用的相关力学参数和强度参数是合理可行的。相关计算成果可为今后类似边坡工程的抗滑桩设计提供参考和借鉴。
Abstract:
In order to study the rationality of using anti-slide pile to reinforce the slope with soft interlayer, a natural slope was taken as an example. The stress-strain state and stability of the slope before and after reinforcement with anti-slide pile were calculated by using the finite element method and strength reduction method. The results showed that the anti-slide piles could effectively prevent the further deformation and plastic zone expansion of the potential landslide mass. After reinforcement, the overall stability of the slope was significantly improved, and the risk of the overall collapse of the geological disaster was controlled. The stress and deformation of the anti-slide pile were within the allowable range of design, which showed that the relevant mechanical parameters and strength parameters used in the design of anti-slide pile were reasonable and feasible. The relevant calculation results could provide reference for the design of anti-slide pile in similar slope engineering in the future.
