摘要
该文结合无锡清明路矮塔斜拉桥主桥的方案设计,针对桥面宽度30m,单根索力超过1000t,主梁索距为7m的矮塔斜拉桥索区横梁进行空间及平面受力分析,通过分析对比,得出准确的横梁受力特性及横向钢束配置。
According to the scheme design of the main bridge of Wuxi Qingming Road Low Pylon Cable-stayed Bridge,the article analyzes the space and plane stress of crossbeam in the cable area of low pylon cable-stayed bridge by aiming at 30-m deck width,1000-t over single cable force and 7-m cable distance of main beam.After analysis and comparison,the article gives the correct stress characteristic of cross beam and the cross steel strand layout.
