摘要
应用核磁共振找水仪测试成果,分析确定滑坡各层岩土体的含水量、孔隙度、渗透率、渗透系数。根据含水量的变化,确定滑坡结构特征、地下水分布及各层滑动带位置。与钻孔资料的对比分析表明,该技术的分析结果与钻孔数据吻合较好,可为建立符合实际的滑坡模型提供可靠依据。
Based on the testing result of the nuclear magnetic induction system(NMIS),the water content,porosity,permeability, permeability coefficient were calculated;according to the feature of the water content depth,the landslide structure,aquifer and sliding zone were determined.Comparing with the drill column,we can see that the NMR result is accordant with the drill-column.The NMR result can supply reliable data for landslide modeling.
