The expected outcome of this research is the availability of an innovative methodology for the safety assessment of aged concrete dams. Most of the concrete dams built in Australia and elsewhere have been in service for over 50 years. Degradation effects on aged concrete dams, and resistant ability of such aged concrete dams against hostile natural events, such as earthquakes, are of great concern for engineers. The safety assessment of aged concrete dams can be done rationally by the proposed method which will provide a better knowledge of the ageing effects on concrete dams. The approach will provide a tool for rational decision-making as to the structural rehabilitation of large concrete dams affected by ageing degradation.

这项研究的预期成果是一个创新的方法，为老年混凝土坝的安全评估的可用性。澳大利亚和其他地方建造的大部分混凝土大坝已经使用了50多年。老化混凝土坝的退化效应以及老化混凝土坝抵抗地震等不利自然事件的能力是工程师非常关注的问题。该方法可以合理地对老化混凝土坝进行安全评估，从而更好地了解混凝土坝的老化效应。该方法将为受老化退化影响的大型混凝土大坝的结构修复提供一个合理决策工具。
