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。
Briefly describing the characteristics of saline soils, and illustrating the practical basis for the in situ permeation tests of saline soils, the particle composition characteristics of saline soils on a foundation of Mangya Town in the west of Qinghai Province and the instruments and selection methods for determining the penetrating test were introduced. Different depths of the distribution of test points and soil characteristics; through experimental analysis of each test point of the infiltration test data, the use of high-density resistivity method to determine the penetration of water injection point of the test results were analyzed and compared to draw the western part of Qinghai salt Permeability of soil and the law of permeability coefficient decaying with depth.
