通过对陕甘宁晋地区黄土滑坡震害资料的分析,提出了地震滑坡最大致灾距的确定方法.依据区内80个地震的滑坡震害资料的非线性拟合,初步建立了地震震级(5.5≤Ms≤8.0)与地震滑坡最大致灾距的定量关系.为了更精确地分区研究这种关系,还进一步讨论了地震滑坡灾害的主要影响因素.
Based on the analysis of seismic damage data of loess landslides in the Shanxi-Gansu-Ningxia region, the method of determining the maximum disaster-induced distance of landslides is proposed.According to the nonlinear fitting of the landslide seismic data of 80 earthquakes in the region, the earthquake magnitude 5.5≤Ms≤8.0) and the maximum disastrous distance of earthquake landslides.In order to study the relationship more accurately, the main factors affecting the landslide disaster are discussed.
