  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、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;場地特徵頻越接近樁基自,樁基地震響應越大,等於自時,由於發生共現象,樁基響應值最大; 3 )樁土剛度越大,樁土之間的相對位移的值越大; 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。
  2. When the frequency approaches zero, the factor approaches zero correspondingly ; 2 ) the amplitude of interaction factors changes with the incident angle of rayleigh waves and reaches maximum when is zero. moreover, with the increase of, the wave period shortens apparently ; ( 3 ) the amplitude of interaction factors decreases as the pile spacing increases and approaches to zero when the pile spacing is 15 ; 4 ) the amplitudes of interaction factors increase clearly with the increasing stiffness ratio of pile to soil ; 5 ) the lat eral seismic response of fixed - head pile groups is much smaller than that of free - head pile groups. moreover, the pile - group effects induced by rayleigh waves can be neglected ; 6 ) the lateral seismic response of piles at different location differs from each other

    得到了以下結論: 1 )樁的相互作用因子隨頻性變化,在動頻較低的情況下,樁的橫向相互作用因子也較低,當頻趨近於零時,相互作用因子也趨近於零; 2 )樁的相互作用因子的值隨瑞利波入射角度的變化而變化,在= 0情況下值最大,且隨入射角度的增加,波動的明顯縮短; 3 )樁的相互作用因子的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 )在頻較低時,相互作用因子值隨樁土相對剛度的增加而顯著增加; 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。
