伊泰普工程设计和施工中的风险分析与管理

1　引言伊泰普水电工程为巴西和巴拉圭两国共有,并共同管理和运行。1970至1974年,对两国共有的巴拉那河界河河段,进行了广泛的可行性研究,确认了工程的规划设计方案。工程施工始于1975年5月2日。1978年10月20日实现了明渠导流。1982年10月23日水库蓄水至溢洪道高程。首台700ＭＷ机组于1984年5月5日开始投入运转。1991年4月10日,装机总容量12600ＭＷ水电站的第18台机组投产。对这个巨型工程的规划、设计和施工过程中进行关键决策时,应用风险分析与管理方法的若干成功实例予以介绍。工程最终的成功,包括其安全性、长期运行的可靠性以及工程的…

Effective Risk Analyses and Management during Design and Construction of Itaipu Hydro Project

Itaipu Hydroelectric Project, jointly owned and operated by Brazil and Paraguay, was conceived during 1970-74, when extensive feasibility studies of the binational reach of Rio Parana were performed. This report cites several examples of practical and effective methods of risk analysis and management that were employed in making critical designs during the planning, design and construction of this megaproject. The ultimate success, including safety, long-term operational reliability and the earliest completion and generation of electric energy, in large measure is attributed to the objective risk analyses that supported timely, often costly, major decisions that were made by the management of Itaipu Binational (ITAIPU).
