备注

简要介绍了滇南、滇西南强震台网,并对玉溪市、红河州、普洱市、西双版纳州67个强震台场地剪切波速进行测试,并根据测试结果计算等效剪切波速,来划分台站的场地类别。分析了台站布设的合理性,为获得强震数据和强震记录的分析处理提供基础资料。

We briefly introduce the strong earthquake networks in southern and southwestern Yunnan, site tests for shear wave velocities, and station site classification based on the equivalent shear wave velocities calculated from the test results for the 67 strong earthquake stations in municipalities and prefectures of Yuxi, Honghe, Pu'er, and Xishuangbanna. We also analyze the rationality of the station deployment so as to provide basic materials for strong earthquake recording and data processing.
