我国地震工作部门在完成地震监测预报的同时,为重大工程和城市抗震防灾作了大量的工作。据不完全统计自1970年以来,地震部门已为2000多项工程建设项目提供了地震基本烈度,地震小区划等,其中大、中型项目约200项,取得了明显的社会效益和经济效益。远在50年代末,我国科学工作者就对位于珠江上游的新丰江水库的地震活动性及抗震防 While completing the earthquake monitoring and prediction, China’s earthquake department has done a great deal of work for major projects and urban earthquake disaster prevention. According to incomplete statistics, since 1970, the earthquake department has provided basic earthquake intensity and seismic zoning for more than 2,000 construction projects, of which about 200 are large and medium-sized projects and have achieved obvious social and economic benefits. As far back as the late 1950s, our country’s scientific workers had discussed the seismicity and earthquake resistance of the Xinfengjiang Reservoir in the upper reaches of the Pearl River
