Abstract

Abstract: The determination of the vehicle location layout process for bridge static test was seen as a constrained optimization problem of vehicle location, vehicle direction, vehicle type, occupying lane number as design variables. The efficiency of non-load-sectional is not excessive which was taken as the constraint conditions. The efficiency of loading section and total number of vehicles was taken as the objective function. The discrete variables were dealt with continuous processing by rounding method. The complex method was used for the optimization calculations. It is demonstrated that the method is suitable for bridge static test in the determination of vehicle position and the efficiency of non-load-sectional is not excessive.

Key words: bridge engineering, load test, vehicle layout, complex method, optimal design

摘要： 将桥梁静载试验中车辆布置位置的确定过程视为以车辆布置位置、车辆行驶方向、车辆类型和占用车道数等为设计变量，以非加载截面加载效率不超标为约束条件，以加载截面效率和车辆总数为目标函数的有约束优化问题，利用圆整法对离散变量进行连续化处理，采用复合形法进行了优化计算。结果表明：此方法能够快速确定桥梁静载试验中的车辆位置，且保证非加载截面效率不超标。
