a.水平外边界上的单元号分别是20,40,60,80他们的水平应力分别是3.38591, 3.44523, 3.44953, 3.41703单位都是MPa和水平分布荷载3.4MPa相比较误差小于0.5MPa

b.竖直外边界上的单元号分别是100,120,140,160他们的竖向应力分别是5.80125, 5.80617, 5.7994, 5.78816单位都是MPa和竖向分布荷载5.8MPa相比较误差小于0.5MPa

c.计算模型竖向约束反力分别是-2.83161,-5.60467,-6.3225,-7.13968,-8.10222,-9.26477, -10.69146,-12.46017,-14.6699,-17.46171,-9.85121之和为-104.4。而作用模型上表面的竖向{1.63761E,19}.

荷载为6×3×5.8=104.4,因此误差小于0.005MN

d.计算模型水平约束反力分别是-4.86901,-6.94898,-6.75913,-7.1305,-7.83428 -8.81682,-10.07665,-11.63689,-13.54497,-15.88009,-8.50264之和为-102。而作用模型右表面的水平荷载为6×5×5.8=102,因此误差小于0.005MN 因此验算之后计算正确

2、分析应力、位移分布:

a、邻近水平轴各单元水平应力与竖向应力和单元横向坐标的关系曲线图 1

{1.63761E,19}. {1.63761E,19}.

b、邻近竖直轴各单元水平应力与竖向应力和单元竖向坐标的关系曲线图
