| 摘 要： | 通过分析云南历史破坏性地震震害异常影响因素，得出第四系软弱土层和新近系禽煤岩层等软弱岩土因素是显著影响云南历史地震震害异常的原因。利用1：20万（中比例尺）地质及水文地质资料，对云南地震重点监视防御区软弱岩土进行调研，得到软弱岩土的分布状况．并初步分析了软弱岩土的分布特征。同时，通过分析对覆盖整个昆明盆地的新生代沉积相作过较详细研究工作的1：5万地质资料，得到昆明盆地软弱土的分布及特征。

| Abstract: | The author analyzed influencing factors on seismic damage anomalies of destructive earthquakes in Yunan.The results showed that the soft rock soil factors,soft soil of Quaternary System and coalbed methane of Neogene System,were the most important influencing factor.Using the medium scale geology and hydrogeology data,the investigation of soft rock soil was done in the key area for earthquake surveillance and protection in Yunnan,and then we got the distribution and its distribution characteristics of the s... |
