摘　　要：探计了以增设冗余单元来提高在役生命线网络系统的抗震可靠性。通过对可增设单元进行重要度分析、并考虑地震环境下的失效相关性，讨论了冗余单元增设的概念性原则。通过建立增设单元的优化决策数学模型，并利用生命线弧单元设计方案的离散性，建立了增设加固优化设计的实用方法。This paper discusses the adding fro fix units used to increase the aseismic reliability of lifelines network system. Through the importance analysis of added units and based on the failure related analysis under earthquake, the conceptual principle of adding frofix units are discussed. Through the estimation of the optimum decision mathematic model and based on the discreteness of lifelines arc units design plan, the practical method of adding-strength optimum design is suggested.
