赤峰市“8· 16”地震是赤峰市历史上 713年以来最大的一次地震。根据《中国地震参数区划》(GBI80 36 - 2 0 0 1) ,赤峰市北部的阿鲁科尔沁旗、巴林左旗、巴林右旗、林西县等地区设计地震烈度为小于 6度区 ,被划为工程非设防区 ,而“8· 16”地震恰恰发生在区划图的非设防区 ,震级为 5 .9级 ,地震烈度为 7～ 8度 ,由于作为基础设施的水利工程均处于无设防状态 ,因此在此次地震中给地区工程造成了损害 ,其中尤以乌尔吉沐沦河流域水利工程受灾情况最为严重。地震后及时对震区水利工程项目进行了检测 ,对震害影响较大的骨干工程 ,根据发生的地震级别、设计地震烈度进行安全复核 ,对工程抗震不安全建筑物及震后损害建筑物采取应急工程措施 ,防止震害进一步扩大 ,使震害损失降至最低 Chifeng “8.16” earthquake is the history of Chifeng City in 713 years since the largest earthquake. According to “China Seismic Parametric Zoning” (GBI8036-2001), seismic intensity of less than 6 degrees is designed in Aruk’erqin Banner, Bahrain Left Banner, Balin Right Banner, Linxi County in the north of Chifeng City, For the project non-defended zone, and the “8.16” earthquake occurred precisely in the zoning map of the non-defended area, the magnitude of 5.9, seismic intensity of 7 to 8 degrees, as the infrastructure of the water conservancy projects are in a state of non-armed , So in the earthquake caused damage to the regional engineering, especially in Wuerji Mu Lun River basin water conservancy project is the most affected. Earthquake water conservancy projects detected in time after the earthquake, the earthquake damage greater backbone of the project, according to the occurrence of the earthquake levels, the design of seismic intensity for safety review of the earthquake-resistant buildings and earthquake damage to the building to take Emergency engineering measures to prevent further expansion of earthquake damage, so damage losses to a minimum
