| 摘 要： | 本文选取川滇及邻区作为研究区域,根据地震构造环境和震害分布特点,将该地区分为西南地区和盆地地区,选取该地区6级以上的典型历史震例,将其数字化得到等震线数据,通过对这些数据的统计回归分析,分别建立两个区域的地震烈度沿长轴与短轴的衰减关系、各烈度面积与地震震级的关系、破裂长度与震级的关系.同时,综合利用上述关系建立不同的地...

| Abstract: | In this paper,the research area is focused on Sichuan-Yunnan and its adjacent areas.According to the seism-tectonic environment and seismic damage characteristics,the authors divided the Sichuan-Yunnan and its adjacent areas into southwest China region and Sichuan Basin region,and chose the typical earthquake cases over Ms6.0 in history.Then,the authors digitalized the typical earthquake cases and gained the isoseismal line.The authors went on and performed the statistical regression analysis of the gained ... |
