INTRODUCTIONThe L ower Yangtze sedimentary basin in South Chinawas a typical carbonate ram p slightly inclining northwestwardduring the Early Triassic. The rhythmic L ower TriassicGriesbachian is m ainly composed of thin- bedded mudrock andmarl (or lim estone) alternations,which can be observed overthe region.Due to the wide distribution and well- comparativestructures of these cyclic sedim ents,it was proposed that thesedim ents originated from som e periodic regional environmen-tal e…  相似文献

On the Relationship Between the Crustal Strain Rate and Seismicity:Detect the Source-Field Relation from the Crustal Strain Field     

Zhang Guomin  Li Li  and Shi YaolinCenter for Analysis  Prediction  CSB  Beijing  China Graduate School of Chinese Academy of Sciences  Beijing  China 《中国地震研究》1999,(4)

The relationship between the strain cumulative rate (i.e., the crustal strain rate, or CSR in short) and seismic activity is analyzed to develop a new method to determine risky regions for strong shocks within recent years by the recorded crustal strain field. Seismic activity, especially the recurrence period, is different in different areas. Ding Guoyu (1984) pointed out that, for different seismic regions, the difference in the recurrence period of strong earthquakes is mainly controlled by their difference in the rate of the tectonic movement, which is controlled by the seismogenic environment and the tectonic conditions. The method of determining the risky regions for strong shocks from the gradient of vertical strain rates observed in a geodetic survey is preliminarily tested with the earthquakes in recent years; the results show that this method is effective and useful for earthquake prediction. The relationship between CSR and seismicity in a specific region is studied with strain theories, obse  相似文献

Envelope Functions of Time Histories in Seismic Safety Evaluation and Scenario Earthquakes     

Shen Jianwen  Yu Zhan  Shi Shuzhong 《中国地震研究》2008,22(3):297-303

It has been a period of time since the concept of scenario earthquake was proposed, but this concept has rarely been used in seismic safety evaluation in China since then. Meanwhile, because of the uncertainties of magnitudes-distances pairs, there is large arbitrariness while determining the envelope function of time histories in seismic hazard analysis. In this paper, we describe a method to control the envelope functions of the time histories by introducing the most-likely combinations of magnitude and distance of the scenario earthquakes based on a probabilistic method, revise the software of the ellipse model for seismic hazard analysis, and give a computation example.  相似文献
