| 摘 要： | 在Winker弹性地基梁的理论上,考虑地基土体的弹塑性性质、地基弹簧受拉脱开、多结点曲形地基梁单元,在ABAQUS二次开发平台UEL上开发了弹塑性地基梁的单元子程序.以实际P-s曲线出发,导出地基土体的一维弹塑性本构关系,用于计算弹塑性地基梁的基床系数.通过算例验证,对比解析解与数值解,验证了所编制单元子程序的正确性....

| Abstract: | Based on the Winkler elastic foundation beam theory,considering the elastic-plastic property of soil mass,foundation spring disengagement under tension,and multi-node curved foundation beam element,the user element subroutine of elastic-plastic foundation beam was developed on ABAQUS secondary development platform,UEL.Based on the actual P-s curve,the 1D elastic-plastic constitutive relationship of foundation soil mass was derived for calculating the coefficient of subgrade reaction of elastic-plastic found... |
