摘要:
渗透系数是土的重要参数之一.本文结合实际工程,研究了不同取样方式、试验手段和计算方法对粘土和粉质粘土渗透系数取值的影响程度,以及不同负压条件下原状土和击实土渗透系数的变化规律,为准确评价水库蓄水后库区、坝基渗漏情况提供了依据.最后通过对比2种土料按不同比例混合后的试验结果,认为粘土和粉质粘土以3:7比例混合后,力学性能稳定,而渗透系数有很大降低,是良好的筑坝材料.
Abstract:
Coefficient of permeability is one of a key parameter of soil. In this paper, coefficient of permeability of clay and silty clay based on different method, testing method and calculating formula is discussed with engineering practice. Its law of intact sample and compactive sample is also researched based on different consolidation pressure. The law can be used to precisely evaluate the seepage state of dam and reservoir being stored water. Finally, the testing results of mixture with different proportion of clay and silty clay are compared. It is concluded that with the ratio of 3:7, the mixture’s mechanical property is steady, its coefficient of permeability decreases dramatically and it is a good construction material for dam.
