得到了以下結論： 1 ）樁的相互作用因子隨頻率呈周期性變化，在振動頻率比較低的情況下，樁的橫向相互作用因子也較低，當頻率趨近於零時，相互作用因子也趨近於零； 2 ）樁的相互作用因子的幅值隨瑞利波入射角度的變化而變化，在= 0情況下幅值最大，且隨入射角度的增加，波動的周期明顯縮短； 3 ）樁的相互作用因子的幅值隨著樁與樁間距的增加而減小，至s d = 15時，樁的相互作用因子基本趨近於0 ； 4 ）在頻率比較低時，相互作用因子幅值隨樁土相對剛度比的增加而顯著增加； 5 ）樁頂固接可以有效地降低群樁的橫向地震響應幅值，由瑞利波產生的群樁效應可以忽略不計； 6 ）群樁中不同樁位的樁的橫向地震響應是不同的，每根樁所在的樁位對其橫向地震響應有很大的影響；刀樁數的增加並不能減小樁的橫向動力響應。The temperature fields and the surface rayleigh waves generated by a pulsed laser in a thick al pipe are analysed by using a finite element method
