| 摘 要： | 本文针对海底底质对水下噪声传播具有显著影响的现象,选取典型负梯度温度跃层,加载三个典型海底底质,即细砂底质、粉砂底质及黏土-粉砂底质,声波参数为固定值。试验定性分析了浅海海底底质对水下声传播的影响,仿真计算了海底底质对声传播的影响,比较分析了不同底质条件下声波的衰减差异,总结了不同底质对水下声传播影响的特点,并同行参考。

| Abstract: | This article is aimed on the obvious imapct of sound propagation by bottom sediment,and chooses a thermocline of typical negative gradient,calculate the propagation loss on three kinds of bottom sediment which are fine sand、silt and clayey-silt.The parameters of sound wave are constant.The article qualitative analysises the impact of sound propagation on bottom sediment,comparative analysises the characteristic of sound propagation on different bottom sediment under water,and for reference. |

| Keywords: | shallow thermocline bottom sediment sound propagation under water |
