                摘要：高速公路大型车辆较多，其产生的交通噪声多集中在低频，现有声屏障对低频噪声吸收效果不佳，并且
                建设成本过高。为提高声屏障的降噪性能，将多种吸声结构应用于声屏障设计中，提出了一种集吸声复合板、
                多重锥形吸声结构、透明隔声结构以及二次余数扩散体复合结构于一体的组合式声屏障。采用传递矩阵法计
                算分析了各结构的声阻抗和吸声系数；以降噪性、安全性和经济性为目标，建立了声屏障多目标优化模型；选
                用遗传算法进行求解，并进行 TOPSIS 决策，从非劣解集中选出最优解；最后，将优化结果与荣乌高速涉县路
                段已安装的挤压成型混凝土声屏障进行比较。结果表明，优化后的组合式声屏障插入损失提高了 6.3 dB(A)，
                提升 40.9%，其中吸声附加值为 5.8 dB(A)；声屏障建设成本减少了 5.9%；立柱顶端位移减少了 96.2%，满足标
                准最大安全控制位移。研究结果可为高速公路声屏障设计提供参考。

                 Abstract: The traffic noise generated by the large number of heavy vehicles on freeway is mostly concentrated
                 in low-frequency, while the existing noise barriers have poor absorption effect on low-frequency noise and the
                 construction cost is too high. To improve the noise reduction performance of noise barriers, various sound
                 absorption structures were applied to the design of noise barriers. A composite noise barrier that integrates
                 sound absorption composite plates, multiple conical sound absorption structures, transparent sound insulation
                 structures, and quadratic residue diffuser composite structures was proposed. The transfer matrix method is
                 used to calculate and analyze the acoustic impedance and absorption coefficient of each structure; A multi-
                 objective optimization model for noise barriers was established with the objectives of noise reduction, safety,
                 and economy; Using genetic algorithm for solving and making TOPSIS decisions to select the optimal solu-
                 tion from a set of non-inferior solutions; Finally, the optimal solution was compared with the installed extruded
