摘　　要：文章以唐山市某斜拉桥为例,介绍了基于Midas Civil的斜拉桥索力调整分析思路,进行了斜拉桥索力调整计算,列举了零位移法和刚性支撑连续梁法,通过对传统计算方法进行优化,得出更简便实用的计算方法。结果显示,应用新方法调整的索力值更为合理,说明该方法可行,计算思路正确。Taking a cable-stayed bridge in Tangshan as an example,this paper introduces the analysis idea of cable force adjustment of cable-stayed bridge based on Midas Civil,carries out the cable force adjustment calculation of cable-stayed bridge,lists the zero displacement method and rigid support continuous beam method,and obtains a simpler and more practical calculation method by optimizing the traditional calculation method.The results show that the cable force value adjusted by the new method is more reasonable,indicating that the method is feasible and the calculation idea is correct.
