抗滑钢轨桩锚固深度的优化分析

Analysis on the Optimal Anchorage Depth of Anti-sliding Rail Pile

抗滑钢轨桩与传统的抗滑桩相比具有一定优势,但目前对抗滑钢轨桩的设计研究较少,尤其钢轨桩锚固段埋深的研究更少。结合工程实例,在滑坡刚体极限平衡的基础上对钢轨桩锚固深度进行了优化分析,利用plaxis有限元软件分析给出的最优锚固深度比设计少2.2m。节省了工程成本。

In comparison with conventional anti - sliding pile, anti - sliding rail pile have certain advantage, but now little research has been conducted on anti - sliding rail pile, especially in its anchorage depth. Taking an engineering example, this paper discusses the optimal anchorage depth of anti - sliding rail pile based on rigid landside mass limit equilibrium, and the optimal anchorage depth is calculated using PLAIXS program, the given optimal anchorage depth is 2.2 m shorter than designed one, so the project cost can be reduced.
