摘要
运用工程控制论的思想 ,将连续刚构桥与斜拉桥的施工过程视为一随机最优控制过程 ,根据这两种桥型的实际施工情况 ,以确保施工中结构线形与理想施工状态线形一致 ,挠度、内力均在容许范围之内为目的。通过分析比较 ,提出这两种桥型施工控制中的不同之处 ,并以实例进行计算 ,探讨、论证这两种桥型施工控制的计算方法。
Applying engineering control theories, the construction control of continuous-rigid-frame bridges and cable-stayed bridges can be regarded as a random optimum control process, in order to keep the deflection and the stress of structures under construction within range of permission, and the construct line-type coinciding with the ideal one, according to the real situation of such two kinds of bridges' construction. By analyzing and comparing, the method of computing of such two kinds of bridges' construction control is put forth.
