摘　　要：城市轨道交通环评技术导则规定了城市轨道交通噪声预测的方法和参数修正原则,但跨座式单轨噪声预测只是参照执行,且其适用性也未经过验证。为此,根据跨座式单轨列车辐射噪声源强特性、垂向分布、传播衰减、速度特性等现场试验结果,论述了技术导则规定的预测模式中有关参数修正原则与跨座式单轨列车运行噪声预测的适用性,确定了跨座式单轨列车运行噪声预测中主要参数修正方法,并与实际监测结果进行验证,据此可以判断技术导则中预测方法及主要预测参数修正的合理性和有效性。Technical guidelines of EIA has provided the method of noise prediction and the principle of parameters correctionfor urban rail transit, but noise prediction mode for the straddle type monorail trains can just refer to these guidelinesonly and their applicability have not been verified yet. In this paper, based on the results of field test of source intensity properties,vertical distribution, propagation attenuation law and speed characteristics of the straddle-type monorail-train radiationnoise, the applicability of the relevant parameter correction principles and the noise prediction mode in technical guidelinesof EIA to straddle-type monorail-train noise prediction were discussed, the main parameter correction method of straddletype monorail train noise prediction mode was established. The results were validated by the actual monitoring data. Therationality and effectiveness of the technical guidelines of the noise prediction methods and the main parameters correctionwere verified.
