| 摘 要： | 本文根据现场调查资料描述了四川省相邻的两县石渠县和德格县分别发生的Ｍｓ５．１和５．０级地震的灾害情况，并对这两次地震的灾害特征和灾害环境等作了对比。虽然这两次地震的震级相近，宏观震中仅相距约１３０ｋｍ（直线距离），但地震所造成的经济损失和社会影响却相差较大。导致这种灾害明显差异的原因主要是先前的冻胀灾害和自然地理环境以及建筑物场地条件的不同。

| Abstract: | According to the data of the spot investigation, seismic disaster with magnitude 5. 1 and 5. 0 occurred respectively in Shiqu and neighbouring Dege, Sichuan province, are described in this paper. The disaster characteristic and surrounding of two earthquakes have been contrasted. Although the magnitude of two events are almost indentical and the distance between the macro--epicenter is about 130km(strainght line distance), economic losses and social effects caused by Shiqu earthquake is very different from Dege event. The reason resulting in the disaster difference is mainly that freeze-expandeddamage before earthquake, physical geography surrounding and place condition of buildings in Shiqu earthquake area is different from Dege event area. |
