摘　　要：分析了传感器系统尤其是传感器布点位置在桥梁结构健康监测中的重要性,对桥梁结构传感器优化布点作了详细的分类及论述。分析了遗传算法的特点和优点,并将其与传统优化算法作了比较。利用遗传算法研究了宁波招宝山独塔不对称斜拉桥健康监测系统中传感器的最优布点问题。结果表明,用遗传算法进行传感器最优布点具有结果稳定可靠,收敛迅速的特点,能够满足系统的要求。The sensor system, especially the sensor placement, plays an importance part in the research of the health monitoring system of large-span cable-stayed bridge. The various optimum algorithms for the sensor placement at present are classified and discussed. Genetic algorithm is introduced and applied to determining the optimal position of the sensors of the monitoring system of the single-tower cable-stayed bridge of the Zhaobaoshan in Ningbo. Numerical simulation results indicates that this algorithm has a good convergence and ability to get the stable and reliable solution.
