对此，本文从我国城市抗震防灾工作对基础性研究的迫切需要出发，结合我国城市地下管网系统的实际情况，在综合分析了现有国内外相关研究的基础上，以理论探讨和工程实用性并重，对城市地下管网系统的地震可靠性分析方法进行了较为全面系统的研究。 |
| 7. | First of all , it determines the scope in which earthquake might be genetated , the potential seismic sources areas and the upper limit of the earthquake magnitude through the analysis , research and evaluation of the area seismic geological condition of the workzone . secondly , according tothe research of the seismic activity , it also determines the seismic activity coefficients for per potential seismic sources areas , and the delay relation of seismic intensity and seismic accelaration , and then three different seismic intenstities and dynamic strength of bedroch under different probability are given . through the analysis and caculation of earthquake hazard with the analytic approach of probability
首先，对工作区的区域地震地质环境进行了分析、研究、评价，确定了莱芜市可能发生地震的范围、潜在震源及其震级上限等。其次，根据对地震活动性的认识，确定了各潜在震源区的地震活动性参数及莱芜市地震烈度和地震加速度衰减关系，在此基础上用概率分析法对莱芜市地震危险性进行了分析计算，得到了莱芜市在三种不同概率水平下的地震烈度和基岩地震动强度。 |
| 8. | Now the diffuse earthquake has been used in the earthquake hazard analysis for the nuclear power plant . so we collect some records from the small - moderate earthquakes with magnitude between 4 . 0 - 6 . 5 and distance from the source less than 70 km . then we develop the attenuation laws of these earthquakes expecting to reflect the attenuation laws of the diffuse earthquakes
通常为近源中小地震的弥散地震影响是核工程安全性评价中的重要内容，为满足核工程地震安全性评价工作的需要，本文选取了一些震级介于4 . 0 ? 6 . 5之间，距离小于70km的中小地震的近场记录，对这些地震的衰减规律进行了研究。 |
