与传统抗滑桩相比，h型抗滑桩整体抗侧刚度更大，结构受力更合理，能抵抗更大的滑坡推力。但由于发展历史较短，对h型抗滑桩的研究相对较少，其结构设计也不完善。采用数值分析软件Flac3d对h型抗滑桩的结构参数进行优化，结果表明，最优梁刚度为前后桩的3倍，最优后桩深度为后桩长度的0.28倍，前桩深度为前桩长度的0.5倍。
Compared with the traditional anti-slide pile, the h-type anti-slide pile has larger overall lateral stiffness, more reasonable structure stress, and can resist the greater landslide thrust. However, due to the short development history, there are relatively few studies on h-type anti-slide pile, and its structural design is not perfect. Numerical software Flac3d was used to optimize the structural parameters of h-type anti-slide pile, and the results showed that the optimal beam stiffness was 3 times of the front and rear piles, the optimal rear pile depth was 0.28 times of the length of the rear pile, and the front pile depth was 0.5 times of the length of the front pile.
