摘　　要：以某码头工程为例,横向排架按柔性桩台考虑,将实际结构图简化得到其计算简图;基于m法和假想嵌固点法,分别采用弹性嵌固和固端约束模拟桩土相互作用,利用ANSYS建立2种有限元模型计算水平力作用下横向排架的内力和变形;采用SPSS对计算结果进行数据统计分析。结果显示:当显著水平α取0.05时,采用m法和假想嵌固点法计算桩土相互作用对水平力作用下横向排架的内力和变形的影响无显著差异。Taking a certain wharf project for example,the transverse bent is considered by the flexible pile platform,the actual structure diagram is simplified and the simplified calculation diagram is obtianed.Based on the[WTB1X]m[WTBZ]method and hypothetical embedded point method,we use fixed end constraint modeling and elastic build-in modeling respectively to simulate the pile-soil interaction.Two kinds of finite element model are established based on ANSYS to calculate the internal force and deformation of the transverse bent frame under the horizontal force.Finally,SPSS statistical analysis is carried out on the calculation results.The results show that when the significant level[WTB1X]α[WTBZ]is taken as 0.05,there is little difference of influence on the internal force and deformation of the transverse bent frame under the horizontal force when using[WTB1X]m[WTBZ]method and hypothetical embedding method to calculate the pile-soil interaction.
