坑道中木格栅消波器的消波效应试验研究

摘要

In this paper, because of the notable function of the porous structure attenuating shockwaves, large rnnumbers of tests about the machine of wooden lattice have been finished, which were conditioned the same porosity and the rndifferent diameters of the pores, and the results have been compared and analyzed at the same time. The results indicate rnthat the little wooden lattice machine with dense pores have more excellent effects.%该文以多孔结构具有强消波作用为研究基础,系统开展了相同孔隙率条件下,不同尺寸的小、大木格栅消波器的消波效应试验,对试验结果进行详细比较,并对消波机理进行初步分析.结果表明木格栅消波器消波效应显著,在相同孔隙率下,断面孔隙更密集的小木格栅具有更优良的消波性能.
