| 本文综述了拱坝强度裂缝的定量研究，给出了拱坝分载位移法、线弹性和非线弹性三维实体有限元法进行拱坝裂缝随机追踪的框图，给出了按线弹性三维实体有限元法进行拱坝裂缝产状随机追踪的框图，以及指定裂缝位置、按线弹性三维实体有限元法进行裂缝定量分析的框图。最后提出了继续进行拱坝强度裂缝定量研究应当考虑的若干问题。 |
| 英文摘要: |
| The advancement of study on cracking in arch dam is summarized. The flow diagrams for random tracking of cracking in arch dam based on load distribution-stiffness method and linear or nonlinear 3-D finite element methods are presented. The flow diagram for crakcing attitude tracking and for quantitative analysis of cracking at specific locations are established according to the 3-D linear FEM. Problems in quantitative analysis of cracking pending for solution are discussed. |
