- This dissertation proposes an algorithm to solve the problem by constructing transition contours using active contour model . the algorithm considers the transition contours construction as a growing process , so it is based on higher layer knowlege and can ensure that transition contours are similar to trunk contours and branch contours , and also reconstructed transition surfaces at branch points are smooth . the contours are connected using adjacent contours synchronous marching algorithm
采用基于全局的柱体生长法来判断断层间轮廓的相互对应关系；针对轮廓线表面重建中的难点问题?分叉问题，提出了一种基于主动轮廓模型的过渡轮廓构造方法，这种方法从物体主动生长这一角度出发考虑过渡轮廓的构造，能够产生综合两断层上轮廓特征的过渡轮廓，是一种基于全局性高层信息的有效轮廓构造算法；利用相邻轮廓线同步前进法进行轮廓拼接。 - In order to assure that the stress and strain state of structure is secure , the author analyses respectively the objective functions of the reasonable finished state and buckle - cable adjusted phase ; thus , the optimized model based on fga is framed . finally according to the example , the computation datum are compared with the iterative forward analysis method and the optimal control theory . the result shows that this method can be used conveniently and meet the construction and design precision
为了满足大跨度钢管混凝土拱桥施工的安全性与成桥预期的内力状态和拱肋线形，本文结合工程实例，分别对合理成桥状态和扣索索长调整的目标函数的确定进行了分析，将一组多变量、多约束的最小化问题无约束化，从而建立起适合于该问题的遗传算法优化模型，将其计算结果分别与迭代前进法和随机最优控制理论进行了比较；结果表明，采用该方法编制的基于结构计算的遗传优化程序操作灵活，能很好的满足施工和设计要求。
