利用乌兹别克斯坦安格连露天采煤场的工业爆破试验 ,研究了黄土的地震动力学效应 ,对不同烈度区地震裂隙、地震沉陷、滑坡和液化等地震形变进行了分析。认为这些地震形变的发育取决于一系列工程地质和地震因素 ,如黄土的地貌、土层厚度、工程地质性质、土层湿度、沉陷性、变形、稳定性特征以及地下水埋藏深度和土层的静荷载 ,等等。此研究对黄土的抗震性能和建筑安全性评价具有重要意义 Based on the industrial blasting test in the open pit of Anglian in Uzbekistan, the seismic dynamic effects of loess are studied, and the seismic deformations of seismic fractures, seismic subsidence, landslide and liquefaction in different intensity regions are analyzed. It is considered that the development of these earthquake deformations depends on a series of engineering geology and seismic factors such as loess geomorphology, thickness of soil layer, engineering geology, soil moisture, subsidence, deformation and stability characteristics as well as depth of groundwater burial and soil static Load, and so on. This study is of great significance to the seismic performance of loess and the evaluation of building safety
