| 摘要: |
| 采用有限单元法计算并比较了薄碾压混凝土双曲拱坝在坝身无孔、设表孔以及设表孔的同时又增设水平梁和闸墩三种情况下的坝身应力分布．计算结果表明，坝体设表孔及增设水平梁和闸墩对拱坝应力的影响是局部的，主要集中在孔口周边及附近，而对拱坝的下部影响很小． |

| Abstract: |
| Three cases of the stress distribution of a thin RCC double curvature arch dam, i. e. without upper outlets, with three upper outlets, and with three upper outlets and a horizontal beam and piers, are calculated and compared. Results show that the impact of the outlets, horizontal beam and piers on the stress distribution of the dam is local, and that the stress concentration chiefly occurs near the outlets'edge and cannot affect the lower parts of the arch dam. |
