  1. The discrepancies are less than 1 . 5 % for the eigenperiod and 7 . 7 % for the real part of the resonance strength
    采用国际ggp观测网中14台超导重力仪21个长期、稳定、连续的高质量重!
  2. Combining these formulas with some earthquake intensity and site - eigenperiod , the lateral seismic responses of free - head and fixed - head pile groups were calculated
    结合具体的抗震设防烈度和场地特征周期,计算了成层地基中群桩的横向地震响应。
  3. 4 . the tidal gravity observations , recorded with a scg at wuhan , are employed to investigate the influences of the ocean tide loading on the fitted fcn parameters and the local characteristics of the nearly diurnal resonance on the tidal gravity observations . it is found that the influence of different co - tides on the fitted eigenperiod and the real part of the resonance strength of the fcn is very small
    结果表明,不同海潮模型对拟合的fcn周期和共振强度实部影响甚微,差异主要表现在品质因子和共振强度虚部的拟合,通过不同海潮模型改正后重力潮汐观测资料的迭积,可减小海潮模型不确定性的影响,获得fcn共振参数。
  4. 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
    将其解析解与具体的的抗震设防烈度和场地特征周期结合起来,计算分析了成层地基中单桩的横向地震响应,得到了以下结论: 1 )上部结构惯性力对桩的横向地震响应的影响不可忽略; 2 )成层地基中的单桩的横向地震响应主要受地震基本加速度、场地特征周期、上部结构质量的影响,随地震基本加速度、上部结构质量的增大而增大;场地特征频率越接近桩基自振频率,桩基地震响应越大,等于自振频率时,由于发生共振现象,桩基响应幅值最大; 3 )桩土刚度比越大,桩土之间的相对位移的幅值越大; 4 )桩顶固接的连接方式,可以有效地降低地震时单桩的横向地震响应。
