摘要/Abstract

摘要： 分别采用三维弹塑性有限元法和分项系数法，对非整体式和整体式折线重力坝的应力和深层抗滑稳定性进行了计算分析，得出整体式折线重力坝有效地改善了坝体的应力和变形状态，但对提高抗滑稳定性不一定有效的结论，并通过拱梁分载法解释了上述结论。采用高压旋喷灌浆进行加固，并提出了较优的加固范围。

Abstract: 3D elastoplastic FEM and the Partial Coefficient Method have been adopted to analyse the stress and deep anti-sliding stability of non-entirety and entirety polygonal line gravity dam. The results show that the entierly polygonal line gravity dam improved the stress and deformation conditions efficiently, but not always so efficiently in steady conditions. The above conclusion has been illustrated by load sharing between arch and beam. On the basis of these, preferable reinforcement has been put forward.

Key words: entirety polygonal line gravity dam, 3D elastoplastic FEM, Patial Coefficient Method, deep anti-sliding stability
