摘要
地震诱发的地质灾害具有群发性的特点,由于没有统一的强度评估方法,很难对不同震级诱发的地质灾害进行横向的对比分析。以地质灾害释放的能量作为强度评估的依据,采用物理学中摩擦力做功将机械能转化为内能的原理,针对地震诱发的滑坡地质灾害,提出强度评估的指标及方法。以云贵交界处"9.7地震"贵州震区内诱发某典型滑坡地质灾害为例,采用该方法进行强度评估,为评估群发性地质灾害释放的能量大小提供借鉴与帮助。
The geological hazards caused by the earthquake have a characteristic of gregariousness. Since there was no uni- fied activity intensity assessment method, it was very hard to carry out a horizontal and comparative analysis on the geolog- ical disasters caused by different magnitudes. On the basis of the energy released by geological disasters for the strength e- valuation, using the physics principle that friction works and converts the mechanical energy into internal energy, the assess- ment indicators and methods of activity intensity for landslides geological disasters caused by earthquake were presented. A case study relating the typical landslide geological disaster occurred in Guizhou within the region of Yunnan-Guizhou ＂9.7＂ earthquake was conducted to asset the intensity by the proposed method. It provides reference and help for assessing the energy released by gregarious geological disasters.
