Some conclusions are drawn : 1 ) effect of inertial force from superstructures on the lateral seismic response of single pile can not be ignored ; 2 ) the lateral seismic response of single pile induced by far - field earthquake are mainly affected by acceleration mass of superstructure > site eigenperiod. it increases with the increment of accele ration and mass of superstructure. as the site characteristic frequency approaches the self - oscillation frequency of the pile, sympathetic vibration occurs and the value of lateral seismic response reaches maximum ; 3 ) as the stiffness ratio of pile to soil increase, the relative displacement of pile to soil increases ; 4 ) the lateral seismic response of fixed - head pile is much smaller than that of free - head pile
將其解析解與具體的的抗震設防烈度和場地特徵周期結合起來，計算分析了成層地基中單樁的橫向地震響應，得到了以下結論： 1 ）上部結構慣性力對樁的橫向地震響應的影響不可忽略； 2 ）成層地基中的單樁的橫向地震響應主要受地震基本加速度、場地特徵周期、上部結構質量的影響，隨地震基本加速度、上部結構質量的增大而增大；場地特徵頻率越接近樁基自振頻率，樁基地震響應越大，等於自振頻率時，由於發生共振現象，樁基響應幅值最大； 3 ）樁土剛度比越大，樁土之間的相對位移的幅值越大； 4 ）樁頂固接的連接方式，可以有效地降低地震時單樁的橫向地震響應。 -

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。 -
