摘要
通过对常用数值计算方法的分析、对比及评价,运用有限元计算方法,建立了加筋土弹塑性本构模型,编制了加筋土挡土墙在动荷载作用下的通用数值计算程序。筋材与其上下表层一定厚度的填土层共同工作,视为筋—土单元,成功地解决了筋材与土介质的接触问题,较好地解决了墙面板与筋材连接处两个接触面单元的特殊问题,不仅使计算方便,而且也符合实际情况。
By analyzing, comparing and appraising numerical analysis methods in common used,a common analytical programme has been worked out with elastic-plastic stress-strain relationship and finite element method is used to analyze reinforced earth retaining wall under dynamic load. A satisfying solution has been put forward to the contact boundary,which element of reinforcement-soil will be seen a total. The especial problem of the joints of contact face element between plate and reinforcement is solved. It not only calculates convenient but also tallies with the fact.
