| Abstract: | This paper summarizes the latest progress in such major theories and approaches used in the high arch dam safety research as the strength theory, the stability theory, the reliability theory, the damage and fracture theory, the numerical simulation analysis, the geomechanical model test, and the monitoring data reverse analysis. Respective limitations and difficulties for further research are analyzed. Such urgent issues are proposed as strengthening the research on the mechanism of fracture from materials damage to buckling, exploring trinitarian analytical process of the dan-body, dam-abutment and dam foundation, establishing criterions of high arch dam integral buckling, and conducting safety monitoring to the high arch dam in operation by means of microwave detecting and optical measurement. |
