| Abstract: | 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. |
