In South China, there are several small to medium sized basins which are characterized by the abundance of such features as multi-layering, lateral heterogeneity, thick sedimentary covers, variable rock facies, repeated erosions and varieties of faul-ting, etc .. These adverse geological conditions entail corresponding complications in. the application of seismic methods. Examples are disturbances from multiple reflec-tions and lateral waves, variable wave velocities, distortions from deep seated structures...

In South China, there are several small to medium sized basins which are characterized by the abundance of such features as multi-layering, lateral heterogeneity, thick sedimentary covers, variable rock facies, repeated erosions and varieties of faul-ting, etc .. These adverse geological conditions entail corresponding complications in. the application of seismic methods. Examples are disturbances from multiple reflec-tions and lateral waves, variable wave velocities, distortions from deep seated structures and others. All these give rise to difficulties in extracting informations concerning palaeozoic strata. The present paper discusses some of the views and methods to counter these difficulties.

在中国南方有一类中小型盆地,它们的特点是垂直方向的多层结构和水平方向的多级分割,形成复杂的构造格局。复杂性就在于沉积深厚,岩相多变;数度侵蚀,火成常见;断层不少,构造陡倾;起伏频繁,上下不符。因此产生了复杂的地震地质条件和探测的技术问题,诸如各类多次波,侧面波的干扰,复杂断层,各种不整合,尖灭带,速度多变,深层畸变等,造成取得古生代地层内部波组的困难。文中提出了解决这些问题的观点和措施。

The data of more than one thousand earthquakes occurred within the Beijing seismic station network since 1967 have been analysed, using the Wadati method for calculating the velocity ratio of seismic waves (Vp/Vs) for each earthquake. The results show that:(1) For the time period mentioned above, before 13 earthquakes of magnitude ML≥3.5 within the seismic network of Beijing, the velocity ratio values obviously drop around the epicentral area before the main shocks and recover after them, (2) Between the magnitudes...

The data of more than one thousand earthquakes occurred within the Beijing seismic station network since 1967 have been analysed, using the Wadati method for calculating the velocity ratio of seismic waves (Vp/Vs) for each earthquake. The results show that:(1) For the time period mentioned above, before 13 earthquakes of magnitude ML≥3.5 within the seismic network of Beijing, the velocity ratio values obviously drop around the epicentral area before the main shocks and recover after them, (2) Between the magnitudes of the earthquakes and the areas of anomalous values of VP/VS, there appears a linear logarithmic relation, while the lasting period of anomalous velocity values does not have such a relation with the magnitudes. (3) A "waiting period" appears following the conclusion of the velocity ratio anomalies till the outbreak of each of the main shocks. Its duration does not have any clear connection with the velocity ratio anomalies. It seems to indicate the very complicated nature of the earthquake mechanism and difficulty involved in using anomalous velocity ratio variation as a precursory phenomenon for the prediction of earthquakes.

用和达法处理了从1967年至1976年十年内发生在北京区域台网内的千余次地震,求得各次地震的 V_p/V_s.结果表明:(1)在上述时期内发生在台网内的13次 M_L≥3.5的地震前,在主震震中附近地区都有明显的 V_p/V_s 下降而后回升的现象;(2)主震的大小与 V_p/V_s 异常区的面积大致成对数线性关系,而异常持续时间与主震震级之间无明显关系;(3)异常结束后到主震发生之间存在一段“等待时间”,“等待时间”的长短与 V_p/V_s 异常的情况无明显关系.这似乎暗示了本区地震发震机制的复杂性,而且也使得用 V_p/V_s 异常预测发震时间存在困难.

And then author has classtified the tectonic deformation bande and generalized the tecnonic combi-nation among the tecnonic deformation bands in China. Finally,the seismo-geologecal condions about the tectonic deformation bands appearing on land surface and the complicate properties in the process of earthquake rupture refected by the tectonic deformation were discussed.
