1、计算过程分为两个工况：1）完建期2）运行期其对应的荷载分别为：1）完建期=自重 2）运行期=自重+内水压力分别计算分析该模型在对应荷载作用下的变形及受力特点。其中材料特性单位局采用标准单位。即：长度：m；弹性模量E:Mpa；密度：；水的容重：取为0.0098。由于压力水头为50m，故内水压力p=对于该问题边界约束施加为：X向左右两侧UX向约束； Y向模型底部全约束；下面为模型建立及计算的APDL命令流:/BATCH/PREP7!模型建立部分关键点坐标k, 0 , 0 , 0k, 25 , 0 , 0k, 25 , 15.07 , 0k, 0 , 15.07 , 0k, 4.3 , 8.6 ,
