摘要
简述盐渍土的特点,说明盐渍土原位渗透试验切实可行的依据,介绍青海西部地区茫崖镇某地基盐渍土的颗粒组成特性及确定渗透试验所采用的仪器及选用方法,确定不同深度各试验点的分布及土层特征;通过试验分析各个试验点的渗透试验数据,利用高密度电阻率法测定注水点的渗透范围,对试验结果进行了分析比较,得出青海西部地区盐渍土的渗透特性及渗透系数随深度衰减的规律。
The paper presents the feasibility of conducting in-site permeability testing to evaluate the seepage of the saline soils in western Qinghai.The concept of permeability coefficient is also introduced in the paper.The grain size characteristics of the saline soils in Mangya and the selection of the testing equipment for the in-situ seepage testing are also introduced.The test points at various soil depths and soil properties are characterized.The permeability tests procedures and the seepage volume with time curves are provided.The seepage limits in the saline soils are evaluated by the high density resistivity method.
