高含水量水泥土力学特性的试验研究

Experimental Study of Mechanical Characteristics of Cemented Soil with High Moisture Content

结合天津市某地下防渗墙工程,对高含水量水泥土力学特性进行了探讨,介绍了水泥土试样的制备、养护方法和试验方法。通过室内抗压试验及渗透试验,研究了不同水泥掺入比及不同龄期下水泥土的力学性能,获得了水泥土的无侧限抗压强度、变形模量、渗透系数及应力-应变曲线等。水泥土的强度、变形模量都随着水泥掺入量的增加而增大,且养护时间越长,其强度和变形模量也越大。

The mechanical properties of cemented soil with high moisture content are discussed in this paper, associated with a underground project of seepage resistance wall. The methods of preparation, curing and test for the cemented soil are introduced. The study of the mechanical properties of the cemented soil with various cement percentages and different ages were conducted through uniaxial compression and permeability tests in laboratory. And the unconfined compressive strength, deformation modulus, permeability coefficient and stress-strain diagram of the cemented soil were acquired.
