| 1. | Analysis of seismic prognostic and discussion of strong earthquake hazard in yajiang block 雅江地块的震兆分析与强震危险性探讨 |
| 2. | “ earthquake hazard estimation is the most effective way for earth scientists to reduce earthquake losses “地震危险估计是地球科学家减少地震损失的最有效的方法。 |
| 3. | The main purpose of this paper is to articulate the method of network evaluation in the earthquake hazard and to provide with feasible evaluation method based on the data availability 本文的主要目的,在收集与整理系统性的路网评估方法,建立具实务操作性的评估方法。 |
| 4. | Widespread release of earthquake hazards estimates in the san francisco bay area have led businesses and governments to spend hundreds of millions on earthquake preparedness11 对旧金山海湾地区广泛发布和流传的地震危险估计已经导致许多公司和政府对有关准备已花费了数百万美元103 。 |
| 5. | In this paper , base on the synthetic analysis of the earthquake hazard of laiwu city , the anti - seismic fortification standards ( the design intensity and the seismic design dynamic coefficient ) in diferent areas of the city are given 本文在综合分析莱芜市地震危险性的基础上,对莱芜市莱城区抗震设防标准(设防烈度及设计地震动参数)进行了研究。 |
| 6. | So , it is necessary to study the seismic reliability of lifeline systems for the needs of earthquake hazard mitigation . this paper presents some methods for solving these problems , which is based on the fact in our country . the main contents includes : 1 ) the seismic damage behavior of the buried pipeline is analyzed by synthesis 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。 |
