| 摘 要： | ：本文采用全过程仿真粘弹性空间有限单元法,对混凝土坝浇筑块长度进行了敏感分析,共计算了7个浇筑块长度,计算结果表明浇筑块长度愈大强约束区浇筑块中心的最大主拉应力愈小,这一有关浇筑块长度的新概念从力学计算上支持了混凝土坝通仓浇筑。

| Abstract: | The 3-D visco-elastic FEM, for whole course simulation of concrete dam is applied to analyze the sensitivity of the placement block length.The calculation results of 7 kinds of length show that the longer the block,the smaller the maximum principal stress in the center of strongly constrained region of the block.This conclusion supports the idea of adopting whole cabin continuous placing in the construction of concrete dam. |

| Keywords: | concrete dam length of concrete placement block sensitivity analysis visco-elastic FEM whole course simulation |
