摘　　要：本文以系统可靠度为安全性与经济性的综合指标,以建(构)筑物设防烈度作为优化参数,建立了生命线系统及单元抗震设防水平最优决策的数学模型。并以遗传算法作为优化手段,建立了实用优化算法。A genetic algorithm for optimum decision on the earthquake fortification level of the lifeline system is studied in the paper. It is confirmed that the system reliability is taken as a synthesis parameter of the safety and economics. The optimum decision model of the level is built by taking the fortification intensity as the optimum parameter. It is found that the genetic algorithm is used as an optimum measure; the practical optimum algorithm is proposed.
