| 摘 要： | 黄土地区极易形成地震滑坡灾害。现场调查显示，受大地构造单元、基底岩层结构、地形地貌条件、地震烈度、断裂构造和马兰黄土临空厚度等因素影响，地震黄土滑坡的展布形态较为复杂，在空间上分布很不均匀，常表现为片状、带状和线状展布，并在不同区域有不同的发育特点。在地震黄土斜坡稳定性分析和灾害预测中，必须考虑多项影响因子。

| Abstract: | Seismic landslides hazard is encountered frequently in the loess area. The investigation and study showed that caused by the influencing factors of unit of tectonics, structures of floor rock stratum, conditions of landform, seismic intensities, fault, thickness of Malan loess, the distribution of seismic loess landslides is very asymmetrical, which mainly show shapes of patch, belt, line, and there are different development characteristics in different regions. Multinomial factors should be considered in the stability analysis and hazard prediction of seismic loess slopes. |
