On the apparatus and measuring method of silt impermeability .
粉土抗渗强度测定设备和方法研究。
With low voidage , few air vents and strong impermeability , the lifetime of the cells is lengthened .
空隙率低，贯通气孔少，抗渗透性能强，提高槽寿命。
Research on impermeability of aquiclude is the key to realizing mining without destroying water resource under shallow buried condition and analogue simulation is an important method for that .
