摘　　要：为研究蒸压加气混凝土墙在实际应用中的隔声效果,考虑声-固物理场的耦合,首先对比研究了相同厚度钢筋混凝土墙与蒸压加气混凝土墙的隔声性能;其次,考虑蒸压加气混凝土墙厚度对隔声量的影响,对比研究了三种不同厚度蒸压加气混凝土墙隔声性能;最后,考虑墙体构造措施,对比研究了三种不同空气层厚度双层蒸压加气混凝土墙隔声性能。研究结果表明,相同厚度钢筋混凝土墙隔声量比蒸压加气混凝土墙的高;当采用蒸压加气混凝土墙时,随墙体厚度增加,隔声量显著提高,但当增加到一定程度时对隔声性能提高影响不大;采用双层蒸压加气混凝土墙可在一定程度上提高建筑隔墙的隔声性能,随中间空气层厚度的增加,双层墙的隔声性能显著提高。In order to study the sound insulation effect of autoclaved aerated concrete wall in the application,the sound insulation performance of reinforced concrete wall and autoclaved aerated concrete wall with the same thickness is compared and studied based on the coupling of sound solid physical field.Secondly,considering the effect of sound insulation by the thickness of the autoclaved aerated concrete wall,the sound insulation performance of three different thickness of the autoclaved aerated concrete wall was compared and studied.Finally,considering the measures of wall structure,the sound insulation performance of three double-layer autoclaved aerated concrete walls with different air layer thicknesses was compared and studied.The calculation results show that the sound insulation of reinforced concrete walls and autoclaved aerated concrete walls with the same thickness is higher than that of autoclaved aerated concrete walls.When the autoclaved aerated concrete wall is used,the increase of the thickness of the wall increases the sound insulation,but when the thickness of the wall increases to a certain extent,it has little effect on the improvement of the sound insulation.The use of double-layer autoclaved aerated concrete walls can improve the sound insulation performance of building partition walls to a certain extent.and with the increase of the thickness of the intermediate air layer,the sound insulation performance of double-layer walls has been significantly improved.
