摘要
为了研究水薄膜填充沟槽对于土体的隔振效果,采用模型试验的方法,分析空沟与水填充薄膜沟槽对于土体地表振幅的衰减作用,在模型试验中设置空沟与水填充薄膜沟槽进行对比试验,在本试验条件下,结果表明:空沟与水填充薄膜沟槽均具有良好的隔振效果,空沟较之无隔振措施其隔振效果提高17.9%~55%,水填充薄膜沟槽则提高了14.3%~52.5%,水填充薄膜的隔振效果和空沟效果相近;在深度的变化下,空沟与水填充薄膜沟槽均随着深度增加而增加,由0.2 m沟深增长到0.6 m沟深时,水填充薄膜沟槽的隔振效果提高了27.5%~35.7%。
In order to study the vibration-isolated effect of water film-filled trenches on soil,this paper uses the model test to analyze the attenuation effect of empty trenches and water-filled film trenches on soil surface amplitude.The water-filled film grooves were compared by test.The results showed that both the empty grooves and the water-filled film grooves had good vibration-isolated effects.Compared with no vibration-isolated measures,the air grooves increased the vibration-isolated effect by 17.9%~55%,the water-filled film groove is increased by 14.3%~52.5%,and the vibration-isolated effect of the water-filled film is similar to that of the empty groove.With the change of depth,both the empty groove and the water-filled film groove increase from 0.2 m trench to 0.6 m trench,and the vibration-isolated effect of the water-filled film trench is increased by 27.5%~35.7%.
