摘　　要：生命系统是人类生活赖以生存的重要设施。地震中生命线系统的震害特征主要表现在破坏原 因多、机理复杂、破坏形式多样、连锁性强、影响范围大、检测和修复期长、经济损失大等特点。 生命线系统的重要性决定了它在震后应急反应中的特殊地位，提高生命线系统的抗震能力及其快速 检测和修复能力是减轻地震损失的重要措施。Lifeline system, as a very complicated network systems, is a important foundation for daily life of society. The earthquake disasters of the lifeline system show that, when the systems are damaged, it is difficult to check and repair them in a short time, the damage mech-,. anism is multiflod & intricate, and there are a large number of distinctive damage characteristics. Because of the strong dependence of modern society on lifeline systems, fluster and confusion will come as soon as lifeline systems are destroyed, and there will be crucially bad impacts to making a right emergency response plan and act in a high-effective manner. improving the seismic reliability of the lifeline system and enhancing ability to inspect and repair them are pivotal approaches to reduce total loss of the lifeline systems.
