中文摘要：
为了更加安全和经济地进行抗震设计，不仅要防止结构发生倒塌破坏，而且要有效地控制结构的其他破坏状态。在此背景下，基于性能的抗震设计被广泛讨论研究，并且被认为是未来抗震设计的主要发展方向之一，在高坝建设工程领域探讨了发电经济功能的高坝建设方案的风险决策问题，提出了一种在不同震级作用下高坝震害损失的计算方法。通过水位这一变量揭示了高坝动力分析与经济损失量之间的内在联系，并以一算例说明了计算方法的正确性和可行性。
英文摘要：
For the safety and economy in the aseismic design of structures, not only the collapse of structures must be avoided, but also other failure modes should be controlled. In this situation, the performance-based design method, which is regarded as the main design method in the future in aseismic engineering, is studied by many researchers. A method of how to choose the high dam construction scheme is proposed based on the function of electricity-generating of dams. Economy losses caused by different intensities of earthquakes are analyzed. Through water level, the relationship between dynamic mechanics and economy loss is established. An example is presented to illustrate the feasibility of the proposed method.
