摘要:
以近40年来世界范围内发生的20次地震总计800条水平地震记录为基础,从加速度反应谱入手,研究震中距、PGV/PGA比值及震级对水平加速度反应谱特性的影响,提出了一种同时考虑震中距、PGV/PGA比值及震级3个指标的近场地震动选取方法。然后对选取的脉冲型水平地震记录作加速度反应谱研究场地类别、震级、PGV/PGA比值等因素对脉冲型水平地震动反应谱特性的影响。研究表明:(1)PGV/PGA>0.2、震中距D<20 km、6.5 < Mw < 7.0作为近场脉冲型地震动的选择原则具有可行性。(2)PGV/PGA>0.2、震中距20 < D < 50 km、Mw>7.0作为中远场脉冲型地震动的选择原则需要进一步研究。(3)震级Mw>7.0时脉冲型地震动反应谱谱值在中长周期范围内明显增大。(4)PGV/PGA>0.2时脉冲型地震动平均谱谱值在中长周期范围内明显增大。
Abstract:
Based on a total of 800 horizontal seismic records of 20 earthquakes happened in the world in the past 40 years, the influence of epicentral distance,PGV/PGA and magnitude on the horizontal acceleration response spectra is studied, and a near-field seismic selection method considering two indices of epicenter distance, PGV/PGAand magnitudes proposed.On the basis of this, 152 typical pulse-type horizontal seismic records are selected in combination with pulse index. The effects of site type, magnitude and PGV/PGA on characteristics of the acceleration response spectra for horizontal pulse-type ground motions were studied. The research shows the following results:(1)If the PGV/PGA > 0.2,epicenter distance D < 20kmand 6.5 < Mw < 7.0,the spectral value increased obviously in the short period range.(2)If the epicenter distance 20 < D < 50 km,PGV/PGA>0.2 and Mw>7.0, the spectral value increases obviously in the medium-long period.(3)If the magnitude is greater than 7, the average spectrum value increases significantly within the medium and long period range.(4)If PGV/PGA>0.2,the average spectrum value increases significantly within the medium and long period range.
