摘　　要：文章采用ANSYS有限元软件,计算研究某海岛渔港透空式防波堤桩基工程的锚岩桩在不同锚固长度条件下,其锚束受力的特性。基于工程地点的建设条件,选择适当的模拟参数建立锚岩桩数值计算模型,对3种不同锚固长度的锚岩桩进行数值模拟,计算锚岩桩锚固长度变化时的受力值,分析不同锚固长度的锚束轴向位移、应力、轴力以及水泥砂浆粘结力随荷载的变化,以及沿锚固深度的分布规律,确定7 m是该工程锚岩桩合理的锚固长度,其计算方法不仅可用于设计阶段锚岩桩锚固长度的计算,同时也为同类工程进行设计计算锚固长度提供了参考。In this paper,the characteristics of the force of the anchor beam under various anchorage lengths in pile foundation engineering of an island breakwater were calculated by using ANSYS finite element software. Based on the construction conditions of the project site,the numerical simulation model of anchor rock pile was established by selecting the appropriate simulation parameters. Three kinds of anchor rock piles with different anchoring lengths were numerically simulated,and then the stress value of anchor rock pile anchorage length change was calculated.The distribution law of anchor beam axial displacement,stress,axial force and cement mortar cohesive force of the different anchorage length with the changeable load along the anchorage depth was analyzed. It is determined that 7 m is the reasonable anchorage length of the anchorage pile,and the calculation method can not only be used to calculate the anchorage length of anchor rock pile in the design stage,but also provide a reference for the design and calculation of anchorage length for similar projects.
