摘　　要：基于浙江省舟山市武港卸船码头嵌岩灌注斜桩工程,采用Ansys有限元模拟D-P模型的钢套筒-人工基床结构,研究相同荷载条件下基床厚度、土体内摩擦角与钢套筒顶端位移之间的关系,分析得出波浪力、水流力作用时,斜桩钢套筒在人工基床位移约束下的位移变化规律,为大直径嵌岩斜桩人工基床-钢套筒稳桩应用提供参考。Taking the project of the rock-embedded cast-in-place oblique piles in Wugang Ship Unloading Dock Project in Zhoushan,Zhejiang Province,as example,an ANSYS finite element model is used to simulate steel sleeve,on the basis of the D-P model.The interrelations among the heights of the artificial bedding,internal frictional angle and the tip displacement of steel sleeve with the same loading condition are discussed.By research and analysis the displacement changing-rule of the steel sleeve of oblique pile under loads from wave and hydrodynamic forces is indicated.These methods will provide reference for the application promotion of the artificial subgrade and large-diameter oblique cast-in-place pile embedded in rock.
