Safety Analysis and Rehabilitation of the Arch Dam ABSTRACT The arch dam has already become one type of selecting dam mainly using in irrigation works at home and abroad, for the better economy and security. As the dam experience is gradually accumulating, the design theory is ceaseless perfecting, and the construction is improving, the more and more concrete arch dam is being built in complicated foundation, and the dam height is in escalation. Therefore, the research about the arch dam security has been given much more attention. And this article makes a comparison about methods of stress analysis and stability analysis through design feature and stress deformation and the structure form of arch dam and the principle of arch-cantilever analysis. This paper is mainly studying the application about analysis stability in the arch dam shoulder and foundation. The causes of arisen crakes and fracture propagation are studied in this article. It also sums up the new technology at home and abroad and evaluates the measures of protecting the arch dam body. It analyzes the safe factor in a dam and some problem about safety monitors and talks some details about safety observation system. At last, it expounds the significance of safety observation system in arch dam safety monitoring.
