摘　　要：利用斜拉桥中应用成熟的影响矩阵法对自锚式悬索桥合理成桥索力的设计方法进行了研究,通过对信南高速公路桐柏服务区自锚式悬索桥合理恒载索力的分析,指出影响矩阵法能够达到所求目标值,且结构优于最小弯曲能量法,值得推广使用。It applies the influence matrix method which is maturely used in stayed-cable bridge in the research of the design method of the proper cable force of self-anchorage suspension bridge. Through the analysis of the proper initial cable force of self-anchorage suspension bridge in Tongbai service area of Xin-Nan freeway, it points out that influence matrix can achieve the target value and its structure is better than the minimum energy method, and it is worth promoted.
