Based on the simulation algorithms on conditionally merginglayers, jointed elements and different time steps for different zones, some of problems, such as ele ment meshes, merging layers automatically made, the shape of elements, relayedc alculation problem, reasonable time step and initial temperature for boundaries by impounding ahead of time are studied in this paper, and a practical explanati on is presented by simulating the constructing process and analyzing the tempera ture field for Shapai RCC arch dam during its life span, which could be used as one of the references for designer.%在条件并层、接缝单元、分区异步长等仿真分析理论的基础上,进一步研究了网格自动生成与并层问题、单元形状问题、接力计算问题、合理时间步长问题、边界初始温度赋值问题及提前蓄水时温度边界的处理问题等等;并以沙牌碾压混凝土拱坝施工过程温度场仿真分析工程实例,证明其结论可供设计人员参考.
