摘　　要：针对矮塔斜拉桥的结构特性,以主梁弯矩为目标,对斜拉索的布置方式进行了优化处理,研究了无索区的长度变化对主梁弯矩产生的影响,得到了经济、合理的结构形式,从而证实了对矮塔斜拉桥无索区长度进行优化的必要性。In view of the low tower cable-stayed bridge＇s structural characteristics, the article tares the beam benaing moment as me goal, carries on optimized processing to the cable＇ s arrangement way, studies the non-cable area the length change the influence which produces to the main beam bending moment, obtained economically, the reasonable structural style, so as to confirm the necessity of getting optimization on the length of low tower cable-stayed bridge non-cable area.

关 键 词：矮塔斜拉桥 优化 无索区长度 弯矩 结构体系
