中文摘要：
结合黔张常铁路项目对水泥土进行一系列的室内研究试验,试验结果表明：水泥土的重度较原状土有所增加,幅度为1.7%~7.4%。无侧限抗压强度随着水泥掺入比的增加而增大,破坏模式为脆性破坏,呈现倒三角锥形。水泥土的压缩模量随着龄期和掺入比的增大而增加。研究成果可为类似工程的设计和施工提供借鉴。
英文摘要：
A series of indoor test were completed according to the research on cement - soil based on Qian Zhang Chang Railway project. The results indicate that soil with a amount of cement can increase unit weight byl. 7 7.4times. The UCS increases signifieantly with the increase of mixing ratio. Damage model is brittle failure, and nobla cone was found. The compression modulus of cement - treated soil increases with the increase of age and mixing ratio. This study is of conference value in the construction and design of other similar projects.
