| 摘 要： | 提出了一种新的求解任意排列、任意半径的弹性桩对平面SH波的多重散射的理论方法,以解决以往假设单重散射的计算方法中不考虑桩列作为整体屏障从而忽略桩间相互干涉关系的不足,并且可用于分析多排弹性桩对平面SH波的散射性状。在数值计算分析中讨论了散射重数,排间距,桩土剪切模量比,桩数等对双排弹性桩屏障隔离效果的影响,从而对实际工程中利用排桩进行振动污染的治理和屏障隔振设计提出了重要的理论依据。

| Abstract: | A new method is developed differing from traditional ones to figure out the plane SH waves scattered by rows of arbitrarily configured and radius elastic piles.It eliminates the disadvantages of the single scattering hypothesis without considering the coherent phase relations between the waves they scatter.It is an innovative way of studing on multi-rows of elastic piles.The influence factors of screening effectiveness including the orders of scattering,the space between pile-rows,modulus ratio of piles and... |
