该火力发电站距震中约20公里,1976年地震前基本烈度按6度设计。震后,根据有关资料确定位于9度范围。 1973年在拟建场地进行了施工设计阶段的地质勘探工作。厂区位于陡河二级阶地上,地层主要为第四纪沉积层,厚达百余米,成层良 The thermal power station is about 20 kilometers away from the epicenter, and the basic intensity before the 1976 earthquake was designed at 6 degrees. After the earthquake, based on relevant data, it was determined to be located in the range of 9 degrees. In 1973, the geological exploration work at the construction design stage was carried out at the proposed site. The plant site is located on the Grade II terrace of Douhe River. The stratum is mainly Quaternary sedimentary, with a thickness of more than 100 meters.
