摘要:
基于Biot饱和介质波动理论,提出了一种求解P波在饱和土体中遇到任意排列、任意半径的弹性桩列表面的散射理论方法,该方法弥补了以往计算理论无法计算任意布置与桩径的隔离屏障的不足。采用该理论公式对具体算例进行数值计算,研究和考察了桩间距、排间距、桩数、桩土剪切模量比等几何与物理因素对弹性桩隔振效果的影响,计算结果对实际工程中的饱和场地采用排桩进行振动污染治理,运用非连续屏障进行隔振设计有着重要的参考意义。
Abstract:
Based on the Biot’s wave theory of saturated medium, it is proposed a method for solving the P wave scattering at the surface of elastic piles with arbitrarily arranged and arbitrary radius in saturated soil. This method makes up for the shortage of previous calculation theory which is unable to calculate the isolation barrier with arbitrary arrangement and arbitrary pile diameter. The theoretical formulas are utilized for numerical calculation of concrete examples. Then the parameters such as pile spacing, row spacing, pile numbers, shear modulus ratio of pile and soil, etc. are investigated to evaluate the vibration isolation effect. The calculation results has important reference significance to the control of the vibration pollution in actual project and the design of vibration isolation with discontinuous barrier.
