摘  要:掌握隧道噪声分布与特征是开展噪声控制及防治的前提。依托天巴拾贰坡施工隧道现场,通过现场实测探究双线隧道重点区域噪声特征及规律,引入噪声评价数和离散小波变换,揭示主要噪声源能量分布特征,并进行噪声危害分级。结果表明:喷浆噪声与风机噪声在频谱上具有相似性,表现为离散噪声;隧道内噪声治理难的根源问题为不同噪声能量分布规律不同,风机、喷浆类噪声表现为先增加后减小再增大,钻孔噪声表现为先减小再增大;职业伤害分级为钻孔>喷浆>通风机。Understanding the distribution and characteristics of tunnel noise is a prerequisite for noise control and prevention.Tianba Shierpo construction tunnel was established as the prototype,the noise of key regions was measured,the law of noise in key areas was explored.Using discrete wavelet transform,the energy distribution characteristics of the main noise sources in the tunnel were defined,noise hazards are classified.The results show that the frequency spectrum distribution of fan and shotcrete noise is similar,and shotcrete noise is discrete noise.The root cause of the difficulty of noise control in tunnel is the different intrinsic characteristics of different noises.The pattern of energy distribution for fan and shotcrete noise exhibits an initial increase,followed by a decrease,and then another increase,whereas the drilling noise displays a decline initially followed by an increase.It can be graded according to the damage to human body as,drilling>shotcrete>fan.
