Research on Seismic Disaster Risk Assessment in Hunan Province
摘要
Abstract
Based on the latest potential earthquake source division results,the seismic hazard analysis is conducted,and the seismic hazard results under different probability levels in Hunan Province are calculated,which are used as the seismic action input for seismic disaster risk assessment.Based on a sampling survey of typi-cal buildings in various regions of Hunan Province,the seismic vulnerability of regional building groups is revised,and according to the kilometer grid data of disaster-bearing bodies such as houses,population,and gross domes-tic product(GDP),a preliminary assessment of the death toll and direct economic losses caused by seismic disas-ter risk in Hunan province is conducted.The results show that,except for some local areas such as Changde,the overall seismic hazard in the province is not high.However,due to the general poor earthquake resistance of build-ings,the death toll and direct economic losses caused by earthquake action cannot be ignored.Especially in some local areas,under the basic fortification intensity,the death toll and direct economic losses are too high,showing an unfavorable situation of"large losses caused by medium-sized earthquakes".关键词
