| 摘 要： | 用取自京郊某垃圾堆填场的垃圾土样进行渗透试验,比较不同密度情况下渗透系数的差别。试验中同时记录了渗透系数随时间的变化情况。试验结果表明,垃圾土的渗透系数随密度的不同,可以在(10-3~10-7)cm/s之间变动。试验中也发现垃圾土的渗透系数随时间而逐渐减小,大约6天左右趋于稳定。对垃圾土的渗透系数室内试验测定应以观测7天时间为宜。

| Abstract: | The permeability test with different densities of municipal solid waste(MSW) sampled from a suburban building site of Beijing is introduced.The variation of the seepage coefficient with time during the test is also presented.The test results show that with the change of the sample's density the seepage coefficient is able to vary from 10~(-3) cm/s to 10~(-7) cm/s.It is also noticed that the seepage coefficient reduced with time going,the time for the coefficient to become a constant during the test was about 6 days.So it is supposed that to determine the seepage coefficient of MSW it is necessary to keep the test at least one week. |
