不同固化剂对软土渗透性影响的试验研究

Experimental Research of Solidification Agent on Clay Permeability

软土地基加固中渗透性是工程设计的主要参数.现通过水泥、固化剂1、固化剂2对粘土的室内渗透性试验结果,分析了不同固化土分别在不同掺入比和不同龄期时渗透系数变化的规律.试验结果表明,从固化土防渗效果分析,固2土>固1土>水泥土.同时分析了固化土强度与渗透系数之关系.

The permeability is an important coefficient in clay engineering designs. The permeability variation of the clay improved with stabilizer 1 ^# and 2^# and normal cement in different stabilizer mixing ratio and time are studied through the laboratory experiments. It can be used for reference for practice engineering. The relationship of unconfined compressive strength and permeable coefficient is also analyzed.
