- 摘要:
- 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 inthis 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 ce-mented soil with various cement percentages and different ages were conducted through uniaxial compres-sion and permeability tests in laboratory.And the unconfined compressive strength,deformation modulus,permeability coefficient and stxess-strain diagram of the cemented soil were acquired.2006,3(3): 15-18 收稿日期：2005-11-8分类号：TU411作者简介：严驰(1959—），女，湖北人，副教授，1982年毕业于天津大学，现在天津大学岩土工程研究所从事科研和教学工作。参考文献：
