  1. 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。
