摘要
结合1949—2016年区内M_S≥4.5中强度地震灾害对村庄破坏程度统计结果,详细评估了1989年大同—阳高地震(M_S6.1)Ⅷ、Ⅶ、Ⅵ烈度影响范围及住房受损情况,认为砖木结构房屋具有一定的抗震性能,但也存在该区农村住房总体脆弱性降低,而农村常住人口脆弱性依然较高的问题。当地政府、村民应重视房屋抗震设防能力建设,提高房屋整体抗震性能,增强抗震设防意识以降低灾损。
This research made a detailed assessment on influence scope and houses damage caused by Ⅵ, Ⅶand Ⅷ intensity of the Datong-Yanggao earthquake （Ms6. 1） in 1989 combined with statistical results a- bout the extent of the village destruction of medium intensity earthquake disasters caused by Ms ≥4. 5 earthquakes in the research area during 1949--2016 years. The assessment shows that brick-wood struc- ture building has a certain anti-seismic performance, but it also exposed the defects that the overall vulner- ability of rural housing lowered in the region and the vulnerability of rural resident population is still high- er. The local government, the villagers should pay more attention to the construction of housing anti-seis- mic capacity, improve the overall anti-seismic performance of housing and enhance the awareness of earth- quake fortification to reduce disaster losses.
