基于FLAC3D的杂填土边坡抗滑桩加固方案设计研究

运用FLAC3D软件，模拟了某项目杂填土边坡抗滑桩加固边坡的稳定性。通过几种加固方案涉及的抗滑桩组合锚索前后，锚索倾角变化，预应力筋以及桩截面形状等加固形式变化，对锚索、预应力筋、桩截面形状、桩体、桩间挡板等对边坡稳定性、桩体内力、桩间拱形成的影响程度进行分析，确定了合理的加固方案，并将加固方案与按传统方法计算结果进行了对比，验证了结果的可靠性。

FLAC3D-based Study on Design of Anti-slide Piles for Reinforcement of Miscellaneous Fill Slope

With FLAC3D software, the stability of anti-slide pile reinforced miscellaneous fill slope of a project was simulated herein so as to analyze the effects of anchor cable, prestressed reinforcement, pile section shape, pile body and baffle between piles on the slope stability, the internal force of pile and the arching between piles in several reinforcement schemes which involve the cases of anti-slide piles with or without anchor cable, the change of cable inclination, and the change of reinforcement mode, such as prestressed reinforcement or pile section shape. Based on the analysis, the proper scheme was determined with the result compared with the traditional method, which verified the reliability of the scheme.
