摘要
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.
A method of determing the maximum epicentral distance of seismic landslide and the maxi- mum fault distance of seismic landslide is proposed through analysis on data of seismic landslide disasters in Shaanxi-Gansu-Ningxia-Shanxi loess region.Some nonlinear fitting calculations were carried out and a preliminary mathematical relationship between the magnitude 5.5≤M_S≤8.0 of earthquakes and both the maximum distances is developed.Furthermore,the main factors of af- fecting the seismic landslide disasters are discussed in order to study accurately this relationship for different areas.
