大跨度预应力混凝土连续梁桥 ,尤其是节段施工预应力混凝土连续梁的配束设计是一个复杂的动态过程 ,以致按传统方法调束特别繁琐。以配束后结构的应变余能极小为目标 ,将遗传算法用于求解此类问题 ,这样配束设计同时受到几何构造约束及受力性态约束的双重困难 ,转化为按几何构造合理布置所求钢束的问题 ,减小了问题的困难度 ,从而加速设计周期。 The design of long span prestressed concrete continuous girder bridges, especially the prestressed concrete continuous beams with segment construction, is a complicated dynamic process, so that it is particularly cumbersome to adjust the beam according to the traditional method. With the aim of minimizing the residual residual energy of the post-bundle structure, the genetic algorithm is used to solve such problems. In this way, the double-bundle design is constrained by both the geometric constraints and the constrained forces, The problem of steel beams, reducing the difficulty of the problem, thus accelerating the design cycle.
