福建及台湾海峡地震预警工程架构探索   总被引：2，自引：0，他引：2  

王洪涛  陈箴 《福建地震》2004,(2)

福建及台湾海峡是海陆板块碰撞到板内地震活动过渡带 ,东侧毗邻台湾板缘地震带 ,西侧为福建内陆板内地震活动区。这是得天独厚的观测研究大陆边缘地震构造带强震活动及板块动力学的良好地域。当前 ,我国进入全面建设小康社会历史时期 ,为防御地震造成社会灾害 ,实现以人为本 ,防患于未然 ,势必需要建构一个实用化的地震预警工程及其机制。本文即是在对福建及台湾海峡近 30多年以来观测研究的基础上 ,提出应用现代空间技术、数字地震、计算机网络等技术架构地震预警工程与机制的一种设想。  相似文献

Earthquake Disaster Management and Insurance     

TANG Ai-ping~  WEN Ai-hua~ 《地球科学进展》2004,(Z1)

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  相似文献   

Evaluation of soil liquefaction in the Chi-Chi, Taiwan earthquake using CPT   总被引：1，自引：0，他引：1  

Chih-Sheng Ku  Der-Her Lee  Jian-Hong Wu 《Soil Dynamics and Earthquake Engineering》2004,24(9-10):659

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.  相似文献

Mitigation of liquefaction and associated ground deformations by stone columns   总被引：3，自引：0，他引：3  

Korhan Adalier  Ahmed Elgamal   《Engineering Geology》2004,72(3-4):275-291

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.  相似文献

刍议国际地震保险投保率   总被引：1，自引：0，他引：1  

陈宏 《山西地震》2005,(1):25-26

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。  相似文献
