摘要: 目的：为了分析抗滑桩加固边坡的研究现状，厘清抗滑桩加固边坡的作用机制及效果，文章综述了国内外关于抗滑桩加固边坡物理模型试验的文献。方法：首先，在静力、振动、离心受力作用下阐述了抗滑桩加固边坡模型试验的过程，并分析了不同类型抗滑桩在不同岩土体边坡中的作用机制及受力情况；其次，对比分析三类模型试验的优缺点；最后，探究了锚索抗滑桩组合体系在边坡支护中的作用机制及优点。结果：结果表明：抗滑桩加固边坡稳定性高，效果好，锚索抗滑桩组合体系能减小桩身弯矩。结论：三类模型试验均有明显缺点，需要加强模型试验中相似材料的选取、施加荷载途径的优化、监测仪器的精准度，以保证更准确地还原边坡变形破坏的实际过程，获取更有参考意义的实验结论和规律。

Abstract: Purposes: In order to analyze the research status of slope reinforcement by anti-slide pile and clarify the mechanism and effect of slope reinforcement by anti-slide pile, the literature on the physical model test of slope reinforcement by anti-slide pile at home and abroad is reviewed. Method: Firstly, the model test process of slope reinforcement by anti-slide piles under static, vibration, and centrifugal forces is described, and the action mechanism and force of different types of anti-slide piles in different rock and soil slopes are analyzed. Secondly, the advantages and disadvantages of the three model tests are compared and analyzed. Finally, the action mechanism and advantages of the combined system of anchor cable anti-slide pile in slope support are discussed. Findings: The results show that anti-slide pile reinforcement has high stability and good effect, and the combination system of anchor cable anti-slide pile can reduce the pile bending moment. Conclusions: The three types of model tests have obvious shortcomings. It is necessary to strengthen the selection of similar materials in the model test, the optimization of loading channels, and the accuracy of monitoring instruments so as to ensure that the actual process of slope deformation and failure can be more accurately restored, and more meaningful experimental conclusions and rules can be obtained.
