| 摘 要： | 应用有限元压缩柔度矩阵，建立了具有接缝传荷能力多块板的位移计算方法．在此基础上，根据系统识别原理，应用修正牛顿法作为参数调整算法建立了具有接缝传荷能力的弹性地基多块板结构材料性能的反演分析方法．反算结果表明，在相当大的模量初始值范围内，该方法具有稳定的收敛性

| Abstract: | With finite element method and compressed flexible array method,this paper establishes a method calculating displacement of joint slab on elastic foundation.Based on the above and system identification method, this paper also establishes a computing program for backcalculating material properties of joint slab on elastic foundation.In order to speed up the calculation, this paper adopts modified Newton method as parameter adjustment algorithm.The numerical results show that this method can converge to a solution steadily and more quickly. |
