石渠5．1级地震灾害调查
|
摘要
１９９２年１１月３０日四川省石渠县发生５．１级地震，宏观震中位于县城尼呷镇、西区、德荣马乡一带。震中烈度Ⅶ度（弱），等烈度线呈北西向椭圆形分布。建筑物破坏的主要特点是，墙体竖向裂缝多、宽，并出现砖墙房屋比夯土墙房屋破坏重的震害现象。这次地震发生在四川省边远、经济较落后的高原地区，破坏区面积大（Ⅵ度区内面积２４７０平方千米），造成了约４３６９万元的直接经济损失。
The isoseismic curves of the M=5.1 Shiqu earthquake is an ellips shape with a long-axis strick about N40W. Epicentral intensity is less than Seven Degree. The houses in Shiqu County(Wate County is contained). Derongma County and Shiqu Town were damaged heavier than oth-er areas.The principal characteristics of house damage are that many crevices in walls appear ver-tical and broad and that the brick-wall houses damaged heavier than the rammer-soil-wall hous-es. although the earthquake occured on the plateau of the remote region in Sichuan where the eco-nomics is very backward,the direct economic loss are about 43. 69 million Yuan(RMB)since the earthquake damaged large area.
