摘要/Abstract

摘要： 针对复杂竖曲线钢桁梁顶推施工中支点标高调整问题，提出一种基于改进MOPSO算法的优化方法。首先，以顶推过程中主梁最大Mises应力和支点标高调整次数为优化目标，以导梁及主梁应力在允许范围为约束条件，构建了钢桁梁顶推施工支点标高调整多目标优化模型；其次，采用动态调整惯性权重和学习因子，引入粒子高斯变异及基于拥挤度的外部存档维护策略对基础MOPSO算法进行改进，并验证了改进算法性能；最后，将笔者优化方法应用于赣州螺溪洲大桥顶推施工，以验证其适用性。研究结果表明：通过改进MOPSO算法所得的Pareto解集多样性与收敛性均明显优于基础算法；采用优化方法后，顶推过程中主梁最大Mises应力由原方案的118.762 MPa降至102.650 MPa(减小13.6%)，总调整次数由原方案的36次减少为20次(降低44.4%)。笔者优化方法减少了支点标高调整次数，改善了结构受力状态，并提高了顶推施工效率。

Abstract: Aiming at the problem of support elevation adjustment during incremental launching of steel truss girders with complex vertical curves, an optimization method based on the improved MOPSO algorithm was proposed. Firstly, a multi-objective optimization model for support elevation adjustment in steel truss girder incremental launching was established, with the maximum Mises stress in the main girder and the number of support elevation adjustments as optimization objectives, and the stresses of the launching nose and main girder within allowable limits as constraints. Secondly, the basic MOPSO algorithm was improved by dynamically adjusting the inertia weight and learning factors, introducing particle Gaussian mutation, and implementing an external archive maintenance strategy based on crowding; and the performance of the improved algorithm was verified. Finally, the proposed optimization method was applied to the incremental launching of the Luoxizhou Bridge in Ganzhou to validate its applicability. The research results show that the diversity and convergence of the Pareto solution set obtained by the improved MOPSO algorithm are significantly better than those of the basic algorithm. With the optimized method, the maximum Mises stress of the main girder during launching decreases from 118.762 MPa in the original scheme to 102.650 MPa (a reduction of 13.6%), and the total number of adjustments is reduced from 36 to 20 (a decrease of 44.4%). The proposed optimization method effectively reduces the number of support elevation adjustments, improves the structural stress state, and enhances the efficiency of incremental launching construction.

Key words: bridge engineering; steel truss girder; support elevation adjustment; multi-objective optimization; improved MOPSO algorithm
