| 摘 要： | 采用模拟试验的方法探讨了在各种环境因素(水、不同化学溶液、不同浓度以及不同pH值等)影响下的水泥土在各个龄期的力学特性,对其相应荷载位移曲线进行了分析和讨论。得到了水泥土在各种侵蚀环境下的力学特性与时间的关系,并对环境侵蚀条件下水泥土的强度增长规律进行了分析。结果显示各种环境因素对水泥土力学性质均有明显的影响。从时间效应看,随着水泥土中水泥的水化和水泥固化体的形成,侵蚀效应在逐渐减弱。 |
| 关 键 词： | 水泥土 侵蚀 时间效应 荷载位移曲线 |

| Abstract: | An experiment of cemented soil is conducted under unconfined compression in order to investigate the timing effects of cemented soil under various environmental conditions. In different curing periods, mechanical properties of cemented soil are discussed corresponding to ionic strength, values of pH and chemical solutions. The relation between cemented soil mechanical properties under different erosion conditions and time is gained, and the rule of cemented soil intensity increasing under erosion condition is analyzed. The conclusions show that timing effects of cemented soil is obvious under erosive conditions. The results can be used not only to study the failures mechanism but also to establish the constitutive model. |
| Keywords: | cemented soil erosion timing effects load-displacement curves |
