Based on these hot and key spots in construction of high dams at present, Combining one of the 973 plan projects: Study of Global Stability of Geology Engineering System under Interaction of Several Factors(NO.2002CB412707), the dissertation mainly studies the stability anomaly and corresponding shape optimization. The main contents are as follows:The dissertation advances stability analysis method of arch dams based on arch-cantilever method, that is, the stability of arch ring and cantilever are analyzed respectively based on arch-cantilever method and corresponding formula of stability calculation is established. So the calculation methods of dam stress and stability are unified.
