我国的地震区划工作是在中华人民共和国成立以后才开始的,经过无产阶级文化大革命,批判了地震区划工作中的形而上学和不可知论的观点,突破了旧的框框,在大量实践的基础上,得到了进一步的发展。我国的地震区划工作是为社会主义革命和建设服务的,是党和国家为减少地震灾害造成的损失、保障国家建设和人民生命财产安全的一项重要措施。 我国是一个多地震国家,地震分布相当广泛,大部分的省区都曾发生过强破坏性地震。因此,随着国家建设事业的飞速发展,对地震区划工作提出了更高的要求和新的研究课题。目前我国正在编制的全国地震区划图就是在这种发展形势的基础上提出来的。 我国的地震区划图将是反映各地区的地震基本烈度。基本烈度的含义是指某一地区,在今后一定时期内和一般场地条件下可能遭遇到的最大地震烈度。这一概念明确地表明:地震的基本烈度是以今后一定时期内的地震预报为基础的。因此,某一地区的地震区划图,实际上是未来若干年内的一幅地震预报图。这和那些不限时间、永久性地震烈度分布图有着明显的差别。最主要的差别是在于,我们的这种区划图考虑了工程建设和民用建筑使用的年限,要求预报出一定年限内可能发生的最大地震的强度、地点和地震影响场的分布。 在预测未来一定时期内的地震危?
After the founding of the People’s Republic of China, China’s seismological zoning began only after the founding of the People’s Republic of China. After the Great Proletarian Cultural Revolution, it criticized the metaphysics and agnosticism in the seismic zoning work and broke through the old framework. On the basis of extensive practice, For further development. Earthquake zoning work in our country serves for the socialist revolution and construction. It is an important measure for the party and the state to reduce the losses caused by the earthquake and ensure the safety of state construction and people’s lives and property. China is a country with many earthquakes. The earthquakes are distributed widely and most of the provinces and autonomous regions have had devastating earthquakes. Therefore, with the rapid development of national construction, higher requirements and new research topics have been put forward for seismic zoning. At present, the national earthquake zoning map currently being prepared by our country is based on this development situation. The seismic zonation map of our country will reflect the basic earthquake intensity in all regions. The meaning of basic intensity refers to the maximum seismic intensity that an area may encounter in a certain period of time in the future and under normal site conditions. This concept clearly shows that the basic seismic intensity is based on the prediction of earthquakes in a certain period of time in the future. Therefore, the seismic zonation map of a certain area is actually an earthquake prediction map in a certain number of years in the future. There is a clear difference between these maps and those of the unrestricted and permanent earthquake intensity distribution. The main difference is that our zoning map takes into account the years of use of the construction and civil buildings and requires the prediction of the distribution of the maximum seismic intensity, location and earthquake-affecting fields that may occur over a certain number of years. In the forecast of the earthquake in the future a certain period of danger?
