摘要
Abstract
Fumin County is located at the southern end of the northern section of the Pudu river fault Zone.The entire area is in a seismic zone with a seismic fortification intensity ofⅦ degrees(peak ground acceleration of 0.15g)or higher.The seismic fortification intensity in Dongcun Town,Kuanzhuang Town,and Sandan Town along the fault line reaches Ⅷ degrees(peak ground acceleration of 0.20g).The area has suffered from multiple earthquakes in history.To gain a thorough understanding of the current seismic fortification status of buildings and the risk of earthquake disasters in the study area,a systematic review of the seismic structure and historical earthquake conditions of the target area was conducted.Combined with on-site investigations and data statistics of buildings,the seismic performance of buildings and the risk of earthquake disasters were comprehensively analyzed from factors such as the proportion of building structure types and construction quality.On this basis,a series of practical suggestions and countermeasures were put forward to provide scientific references for the reinforcement projects of buildings and the construction of civilian houses in the earthquake-prone area,thereby effectively enhancing the seismic and disaster prevention performance of buildings.关键词
