摘要
通过对淇澳大桥独柱式主塔的横向受力分析 ,发现了在实际工程设计中常常被忽略、数值较小的斜拉索索力的横向水平分力 (扶正力 )具有提高塔柱横向承载力的作用 ,因此设计出较小的塔柱横向尺寸及桥面宽度 ,大大地节省了投资 .
According to the lateral force analysis of the single column tower of Qi Ao bridge, the small lateral horizontal component of the cable force (correcting force) is discovered, which is often ignored in practice and can greatly increase the lateral load carry capacity of the tower. So smaller lateral size tower and smaller width deck of the bridge is designed for the result of reducing the investment of the bridge.
