| 摘 要： | 对基础混凝土浇筑块进行了温度应力有限元仿真计算。研究了40m和60m长单层浇筑块和多层浇筑块在改变材料参数和施工参数情况下的水平约束应力；展示了在时间与空间的叠加效应下，最大水平约束应力与浇筑块长度的复杂关系。其成果可供底宽过大的大坝在选择施工材料、制定分缝方案与施工计划时参考。 |
| 关 键 词： | 材料参数 施工参数 水平约束应力 温度应力仿真计算 混凝土浇筑块 |

| Abstract: | In this paper, a further study on the restraint stress of 40-meter-long and 60-meter-long concrete blocks with different materials and construction parameters is made with the finite simulation methods under the condition of single layer or multi-layer blocks construction. The result could be used for the dams which have long bottom width to choose the construction materials, the longitudinal joint design and the construction plan. |
| Keywords: | material parameter construction parameter horizontal restraint stress temperature stress simulation analysis concrete block |
