變幅激勵(lì)的頻率對(duì)系統(tǒng)穩(wěn)定性有較大影響,當(dāng)變幅激勵(lì)頻率接近系統(tǒng)固有頻率時(shí),系統(tǒng)面內(nèi)外能量交換周期減小,擺幅增大;當(dāng)變幅激勵(lì)頻率等于系統(tǒng)固有頻率時(shí),系統(tǒng)面內(nèi)外均出現(xiàn)共振現(xiàn)象。 - 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(jié)論：1)樁的相互作用因子隨頻率呈周期性變化，在振動(dòng)頻率比較低的情況下，樁的橫向相互作用因子也較低，當(dāng)頻率趨近于零時(shí)，相互作用因子也趨近于零；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(dòng)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sd=15時(shí)，樁的相互作用因子基本趨近于0；4)在頻率比較低時(shí)，相互作用因子幅值隨樁土相對(duì)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(yīng)幅值，由瑞利波產(chǎn)生的群樁效應(yīng)可以忽略不計(jì)；6)群樁中不同樁位的樁的橫向地震響應(yīng)是不同的，每根樁所在的樁位對(duì)其橫向地震響應(yīng)有很大的影響；刀樁數(shù)的增加并不能減小樁的橫向動(dòng)力響應(yīng)。 - 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(shè)防烈度和場(chǎng)地特征周期結(jié)合起來(lái)，計(jì)算分析了成層地基中單樁的橫向地震響應(yīng)，得到了以下結(jié)論：1)上部結(jié)構(gòu)慣性力對(duì)樁的橫向地震響應(yīng)的影響不可忽略；2)成層地基中的單樁的橫向地震響應(yīng)主要受地震基本加速度、場(chǎng)地特征周期、上部結(jié)構(gòu)質(zhì)量的影響，隨地震基本加速度、上部結(jié)構(gòu)質(zhì)量的增大而增大；場(chǎng)地特征頻率越接近樁基自振頻率，樁基地震響應(yīng)越大，等于自振頻率時(shí)，由于發(fā)生共振現(xiàn)象，樁基響應(yīng)幅值最大；3)樁土剛度比越大，樁土之間的相對(duì)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(shí)單樁的橫向地震響應(yīng)。 - It's difficult to find frequency approach in a sentence. 用frequency approach造句挺難的
