中文摘要:
      本文首先介绍斜拉桥索力优化的概念,然后通过广义影响矩阵,介绍了一种实用的斜拉桥索力优化的影响矩阵法,这种方法既可用于确定成桥合理状态的索力,也可用于施工阶段的索力优化和成桥后的索力调整,实现程序化计算十分方程,最后给出其工程应用。
英文摘要:
      \ In this paper, a concept of optimization of cable prestresses of cable stayed bridges is firstly introduced. Secondly, by means of general influence matrix, a practical optimization method of cable prestresses of cable stayed bridges is developed. The method can not only be applied to determine the optimum cable prestresses of the bridges, but can also be used to construction control. The method used in programming is proved to be efficient and easy to realize. Finally, engineering applications of the method is presented.
