关于在地震预报中遇到的几个问题的探讨

地震台站工作人员 ,在进行观测资料分析、地震预报研究过程中 ,往往会遇到的几个问题 :1、手段单一 ,对于前兆现象无法全面表述。 2、如何识别异常与地震之间的关系。 3、如何兼顾点和面的关系。

Earthquake Disaster Management and Insurance

As one of the most powerful tools to reduce the earthquake loss, the Earthquake Disaster Management [EDM] and Insurance [EI] have been highlighted and have had a great progress in many countries in recent years. Earthquake disaster management includes a series of contents, such as earthquake hazard and risk analysis, vulnerability analysis of building and infrastructure, earthquake aware training, and building the emergency response system. EI, which has been included in EDM after this practice has been done for many years, include these contents: insurance model, financing. This paper presents the development of china in EDM and EI. The main contents include: (1) the statue and trend of earthquake disaster management and insurance in china; (2) the progresses and new methods about the seismic risk zonation and vulnerability analysis, and the future developing trend, the application of GIS in earthquake disaster assessment is introduced; (3) the way and illustration in building the earthquake disaster e     

Evaluation of soil liquefaction in the Chi-Chi, Taiwan earthquake using CPT

During the 1999 Chi-Chi, Taiwan earthquake, many sand boiling phenomena were observed in central Taiwan, which caused severe ground settlement and structure damages. According to the installed accelerograms, the peak ground surface horizontal accelerations in the liquefaction-affected areas range from 774.42 to 121.3 gal. The writers carried out an extensive investigation of soil liquefaction in this earthquake. In this paper, we present results of the CPT exploration and post-earthquake liquefaction analysis. Two hundred and seventy five (275) cone penetration test data were collected from the liquefaction-affected areas, and 46 liquefaction case histories and 88 non-liquefaction case histories were derived that can be used to evaluate the accuracy of existing liquefaction evaluation models. In addition, the strength of the liquefied soils after earthquake and the implication of its liquefaction potential in the future event are discussed.     

Mitigation of liquefaction and associated ground deformations by stone columns

Soil liquefaction and associated ground failures have been a major source of damage during the past earthquakes. The risk of liquefaction and associated ground deformation can be reduced by various ground-improvement methods including the stone column (gravel drain) technique. This paper presents the current state of the stone column technologies as a liquefaction countermeasure. A comprehensive review is provided aiming to: (a) identify key considerations for the general use of stone columns as a liquefaction countermeasure, (b) provide insights for design and construction, (c) compile the latest research developments, and (d) identify sources of useful information. Case histories of field applications and observed field performance are cited to portray different stone column applications and observed effectiveness. The paper identifies areas where more research is needed and includes recommendations for future research and development.

介绍了2003年12月1日新疆昭苏6.1级地震的现场考察结果.该地震宏观震中位于受灾最重的兵团农四师76团11连西侧,极震区烈度为Ⅷ度;圈定出Ⅷ度、Ⅶ度和Ⅵ度3条等震线.此次考察还着重考察了震区各类典型建筑的受损特征,对受损原因作了初步分析,所取得的经验可供类似地区抗震设防和民房改造工作参考.     

刍议国际地震保险投保率

地震灾难带来的损失日益增加的问题，让保险业至今难以应对。地震发生频率低、损失巨大而保险公司的承保能力又十分有限，加之，社会公众的投保意识薄弱，造成地震保险投保率过低。从地震灾情入手，介绍了国际地震保险开展情况，剖析了地震保险投保率过低的原因，并针对问题提出了解决措施。     

谈县级地震部门依法管理建设工程抗震设防要求

以山西省祁县依法管理工程抗震设防要求为例，论述了强制性审核、确定一般工业、民用建设工程抗震设防要求的重要性及其深远意义。结合工作实际．总结了部分依法行政、规范管理和落实抗震设防要求的经验。     

发挥地震学会优势促进防震减灾工作--关于加强山西省地震学会管理工作的几点思考

随着我国机构改革的不断深入和社会主义市场经济体制的逐步建立和完善，地震学会同其他社会团体一样将成为现代社会的支柱之一。以山西省地震学会目前的工作现状为例，指出学会在管理体制、运行机制和活动方式等方面存在的问题，提出了发展思路及建议。
