Abstract

Abstract: The geological hazards caused by the earthquake have a characteristic of gregariousness. Since there is no unified activity intensity assessment method, it’s very hard to horizontally analysis the different between all the seismic geological disasters. On the basis of the energy released by geological disasters for the strength evaluation, using the physics principle of friction works convert the mechanical energy into internal energy, put forward the assessment indicators and methods of activity intensity for landslides geological disasters caused by earthquake. Taking a typical landslide geological disaster occurred within the region of Yunnan-Guizhou "9.7" earthquake in Guizhou as an example, provide reference and help for quickly and easily assessing the energy of geological disasters.

Key words: environmental engineering, geological disasters, activity intensity assessment, gregariousness, energy

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。
