摘要
根据桩基码头的结构特点 ,采用空间刚架单元、板单元和桩基单元及其组合模拟码头结构空间受力状态 ,用研制的空间结构内力分析计算程序 ,对南京港某码头进行结构计算 ,并将空间结构的计算结果与平面情况的计算结果进行比较 .分析结果表明 :用空间刚架单元、板单元和桩基单元模拟码头各构件 ,对码头进行空间结构分析是适宜的 ;空间结构的计算结果较平面结构计算结果能更好地反映桩基码头的空间效应和简化计算带来的误差 .
According to the structural characteristics of pile piers, the program for internal force analysis of spatial structures is adopted to calculate a pier structure of the Nanjing Harbor with the spatial rigid frame element, plate element, pile element, and their combination used for simulation of spatial stresses of piers. The calculated results are compared with those calculated by FEM as a plane structure, and it is shown that the spatial structure calculation can well reflect the spatial effect of pile piers and decrease the error induced by simplified calculation.
