【摘要】 根据水库诱发地震的发震相关因素和特点,确定出水库诱发地震数据库元参数和库结构,并通过资料收集初步建立起水库诱发地震数据库,它包含了全世界水库诱发地震震例1 31个、中国大Ⅰ型水库110座、中国大Ⅱ型水库200座和坝高达100m的水库70座,并具有快速查询、统计、图示等简单功能。在汶川M_S8.0地震发生后的第2天,应地震主管部门的要求及时给出了四川省及附近区域已建大型水库的基本信息及分布。可见,水库诱发地震数据库是有助于政府部门进行地震快速对策的一种有效工具。更多还原

【Abstract】 In the paper,according to the related factors and characteristics of identified reservoir induced earthquakes,the parameters of reservoir induced earthquake database and library structure have been determined.Based on the database functions of ARCGIG geographic information system software,the reservoir induced earthquake database contains 131 reservoir induced earthquake cases in the would, 110 Class-Ⅰlarge reservoirs(larger than one thousand million cubic meters),200 ClassⅡlarge reservoirs (larger than one hundred million cubic meters and less than one thousand million cubic meters) and 70 reservoirs with dams higher than 100 meters in China.It has the functions of quick query,statistics and icons.After the Wenchuan earthquake,aftershocks endangered many reservoir’s dams and people who were taking part in earthquake rescue and relief operations.Two days after the Ms8.0 Wenchuan earthquake,the distribution and basic information of large reservoirs in Sichuan Province and nearby regions was submitted.The government made timely earthquake emergency response decisions to ensure a safe relief.The reservoir induced earthquake database is not only a method provided to the government for quick decision-making,but also can be used nation-wide.更多还原
