Study on Vibration Attenuation Effect of Vibration Isolation Trenches in Strong Tamping Foundation Treatment
To effectively analyze the effect of vibration isolation trench on the vibration attenuation of buried pipes in the slope caused by strong ramming construction.In this paper,the strong ramming construction of a base project in Qingdao was taken as the research background.ANSYS/LS-DYNA finite element software was utilized to create a three-dimensional model of rammer-slope-buried pipes.Furthermore,the effect of the vibration isolation trench's placement and the depth of the vibration isolation trench on the vibration speed of pipes was studied by altering their positions.The results indicated that the vibration isolation trench has a notable influence on the radial vibration speed of the pipe in comparison to the vertical vibration speed,and the maximum vibration velocity of the pipe appears in the lower left part of the pipe.When the depth of the vibration isolation trench is greater than 2 m,the vibration reduction effect of vibration isolation trench at the top of the slope is better than that of vibration isolation trench at the foot of the slope.The findings of this research can serve as a valuable referenc for the vibration control of strong ramming construction and the safety protection of buried pipelines.
