摘要
边坡的地震稳定性受到边坡的岩土特性、地形地貌、地震地质 ,大气降雨等多种因素的影响 ,而且这些影响因素难以精确确定。将天然边坡看作是部分信息已知、部分信息未知的灰色系统 ,用灰色理论中的灰色聚类方法预测其地震的稳定性。通过将预测结果与边坡的实际震害作对比 ,讨论了灰色聚类法的有效性和局限性
The stability of slopes during earthquake is affected by manifold factors, including properties of rock-soil, topogrsphy, geology, seismicity and rainfall etc and it is difficult to determine influence of these factors exactly. The natural slope subjected to earthquake is thought of as a grey system with partly known and partly unknown information and the grey clustering method of grey system theory is used to predicting its seismic stability. The effectiveness and limitationas of the grey clustering method are discussed by the aid of comparison between predicted results and practical performance of slopes during earthquakes.
