A retaining form of a shock-absorbing antislide pile is proposed for slope engineering. A flexible material (shock-absorption layer) is filled in front of an ordinary antislide pile, which is used to absorb a large amount of seismic energy, thereby decreasing the transmission of seismic energy to the antislide pile. The flexible material thus reduces the seismic response, hence improving the aseismic capacity of the antislide pile. To verify the seismic performance of the shock-absorbing antislide pile, a shaking table contrast test was conducted and the results were compared with those from an ordinary antislide pile. The test results show that the flexible material absorbs a portion of the seismic deformation of the slip mass, decreasing the final displacement of the shock-absorbing antislide pile compared to that of the ordinary antislide pile, thereby reducing the sensitivity of the pile body to the displacement. Under the same conditions, the acceleration response of the slope body at the same height is lower for the shock-absorbing antislide pile than that for the ordinary pile, with the seismic performance of the former being superior to that of the latter. Furthermore, the shock-absorbing antislide pile is similar to the ordinary pile in terms of the dynamic earth pressure distribution form of the pile shaft; however, its value is relatively smaller, and the former exhibits better dynamic stress performance than the latter. The test results should prove useful for aseismic design of slopes.

地震作用下新抗滑桩的振动台试验

提出了一种减震防滑桩的固定形式，用于边坡工程。柔性材料（减震层）填充在普通防滑桩的前面，用于吸收大量的地震能，从而减少了地震能量向防滑桩的传递。因此，柔性材料降低了地震响应，从而提高了抗滑桩的抗震能力。为了验证减震防滑桩的抗震性能，进行了振动台对比试验，并将结果与​​普通防滑桩的结果进行了比较。测试结果表明，与普通抗滑桩相比，柔性材料吸收了部分滑移体的地震变形，从而减小了减震抗滑桩的最终位移，从而降低了桩身对位移的敏感性。在相同条件下，减震防滑桩在相同高度下的边坡加速度响应要比普通桩低，前者的抗震性能要优于后者。此外，减震防滑桩在桩身的动土压力分布形式上与普通桩相似。但是，其值相对较小，并且前者具有比后者更好的动态应力性能。试验结果应证明对边坡的抗震设计有用。减震防滑桩在相同高度下的边坡加速度响应要比普通桩低，前者的抗震性能要优于后者。此外，减震防滑桩在桩身的动土压力分布形式上与普通桩相似。但是，其值相对较小，并且前者具有比后者更好的动态应力性能。试验结果应证明对边坡的抗震设计有用。减震防滑桩在相同高度下的边坡加速度响应要比普通桩低，前者的抗震性能要优于后者。此外，减震防滑桩在桩身的动土压力分布形式上与普通桩相似。但是，其值相对较小，并且前者具有比后者更好的动态应力性能。试验结果应证明对边坡的抗震设计有用。其值相对较小，前者的动应力性能优于后者。试验结果应证明对边坡的抗震设计有用。其值相对较小，前者的动应力性能优于后者。试验结果应证明对边坡的抗震设计有用。
