| 摘 要： | 通过分析和归纳近年来水泥土研究成果，总结了水泥土的渗透和强度特性，并提出了水泥土耐久性和腐蚀性问题。水泥掺入比是影响水泥土渗透和强度的主要因素，渗透系数随掺入比或龄期的增加而减小，并趋于一定值。相同水泥掺入比条件下，龄期是影响水泥土渗透系数的主要因素;强度随掺入比或龄期的增加而增大，外掺剂是否改善水泥土强度取决于外掺剂的自身性质，强度随水灰比的增大而减小。应力应变曲线型态与围压相关，低围压下为软化型，并随围压的增大向硬化型发展; 剪切破坏面上法向应力与轴向夹角Θf随着围压增加而减小。

| Abstract: | The researches of cement-soil in recent years are summed up.The permeability and strength properties of cement-soil are summarized and the durability and corrosion problems are put forward.Cement ratio is a main factor affecting the strength and permeability coefficient of cement-soil.Permeability coefficient decreases with the increasing of cement ratio or age and approach to a constant.Under the same cement ratio conditions,age is the key of permeability coefficient of cement-soil.Strength has a positive ... |
