摘要
在黄土台塬地区,由于过量引水灌溉导致塬边滑坡频繁发生。本文以24起甘肃黑方台滑坡及11起陕西泾阳南塬滑坡为研究对象,分析台缘地区滑坡滑动距离与滑体各参数之间的关系,结果显示滑距与滑体体积、宽度及厚度的关系较为明显,并以表征滑体形态的滑体长度、宽度及厚度作为计算滑距的指标,通过多元线性回归及模糊信息优化法量化滑体参数与滑距之间的关系,计算滑距,并对计算结果进行对比,结果表明其计算值与实际值吻合度都较高,可为滑距的计算及统计提供参考。
Loess landslides developed frequently on the edges of loess platform because of overirrigation.With 24 landslides at Hei Fangtai in Gansu province and 11 landslides at South Jingyang Plateau in Shaanxi province as the research objects,analyzed the relationship between sliding distance and parameters of sliding-body on the area of edges of loess platform,the results showed that the relationships between sliding distance and landslide volume,width,thickness are obvious,and the parameters of landslide length,width and thickness which have no correlation each other can represent the sliding-body form as factors,calculated the sliding distance by the Multiple Linear Regression and Fuzzy Information Optimization method,then compared the calculation results and the actual sliding distance,the results displayed that both calculated values had a good coincide degrees with actual value,so they can provide the references for the calculation and the statistics of sliding distance.
