A method for predicting the phase spectra of strong ground motion is presented based on the equivalent dispersion of wave motion and the approach for synthesizing ground motions is then studied. It is found by studying the model of equivalent dispersion using SMART-1 array records that the phase of the stochastic process η(f),which characterizes the randonmess of the fourier phase of strong ground motion, obeys the normal distribution in the range [0,2π]. The discovery is then used to improve equivalent dispersion...

A method for predicting the phase spectra of strong ground motion is presented based on the equivalent dispersion of wave motion and the approach for synthesizing ground motions is then studied. It is found by studying the model of equivalent dispersion using SMART-1 array records that the phase of the stochastic process η(f),which characterizes the randonmess of the fourier phase of strong ground motion, obeys the normal distribution in the range [0,2π]. The discovery is then used to improve equivalent dispersion model. The improved model is further extended to predict the phase spectra of strong ground motions within a field. Both the deterministic phase relation of adjacent points caused by the traveling wave and the randonmess caused by a number of complex factors are considered in this model. The method is checked by comparing synthesized and observed accelerograms, absolute acceleration spectra and intensity envelopes of ground motion using the SMART-1 array data.

本文在强震地震波频散研究的基础上,进行了强地震动场相位预测方法和多点地面运动时程合成方法的研究。作者首先运用SMART—1台阵资料对强地震波等效频散模型进行了深入研究,发现表示地震动相位随机性的随机过程η(f)的相位服从正态分布,并用此分布取代了原模型中的均匀分布的假定。然后将这一改进的等效频散模型推广应用于强地震动场相位的预测。论文中提出的方法既考虑了相邻点相位的行波相关性,亦考虑了多种复杂因素产生的随机性.最后,利用SMART—1台阵记录,通过合成的地震动场的时程曲线、绝对加速度反应谱和强度包线与相应观测结果的对比,对建议的方法进行了检验,论证了这一方法的可行性,并对今后研究工作作了简要讨论。

The complex resistivity well logging with electrode antenna was developed on the basis of the theoretical and experimental study of rock physical property.The basic theory of the logging method is the electrical dispersion property of rock.The resistivity,permittivity and the dispersion of formation can be measured using a logging tool with a high-frequency(about 10 kHz) channel.The logging data can be interpreted by the inversion algorithm.The complex resistivity dispersion function from core experiment is taken as the forward model.The real component resistivity of low frequency and the module of complex resistivity of high frequency can be inversed to calculate the apparent water saturation and evaluate the oil-bearing property of reservoir. Field application of this method proved its possibility in log interpretation.

电极法复电阻率测井技术是以岩石复电阻率频散特性为理论依据,从岩石物理性质的理论和实验研究的基础上发展起来的一种新型电测井方法,该方法能同时检测岩石电阻率、低频介电常数和频率响应特性。电极法复电阻率测井的实现是在双侧向仪器的基础上增加一个频率大约为10kHz的高频通道,并检测其复电阻率模值。其测井资料的解释用岩心实验建立的复电阻率频散模型作为正演模型,对测量到的低频实部电阻率和高频模值电阻率进行反演求出地层的含油气指示参数,从而评价地层的含油气特性。应用该方法进行了现场测井和资料处理,结果表明其方法具有可行性。
