摘要
在对盐渍土现场与室内渗水实验结果差异分析的基础上,对西藏扎布耶盐湖盐渍土的渗透性进行了研究.为使所测渗透系数更能接近实际,提出了用原位渗透实验方法来评价土层垂直渗透性能.利用数学模型得到了计算渗透系数的相应公式.结合实际工程证明该测试方法和计算公式是可行的.
The permeability of saline soil in Zabuye salt lake in China was studied based on the analysis of difference between the results of saline soil in-site test and indoor seepage test. In order to make the tested values of permeability coefficient more accurate, an in-site permeability test method was proposed to evaluate the verti- cal permeability of soil. The formula for calculation of permeability coefficient was established from a mathematical model. An engineering application demonstrated the applied testing method and the formula were reliable.
