| 摘 要： | 土木工程中广泛使用的软土地基加固方法主要有水泥土搅拌法、旋喷法、注浆法等，其原理主要是形成具有一定强度和稳定性的水泥土加固体。在我国广大地区地下水受工农业、生活以及海水等环境因素的影响，常含有一些具有侵蚀性的离子，如 ， , 等。通过模拟试验的方法，探讨了各种侵蚀性的离子在不同浓度和不同pH值条件下对水泥土的力学效应，并对环境侵蚀机理进行了探讨。试验结果表明，水化学作用对水泥土的力学性质具有明显的影响，对水泥土在复杂地质环境条件的设计和工程应用具有重要意义。

| Abstract: | The soil-cement pile foundation was widely used to improve soft foundation in civil engineering. Some erosive ions, which lie in groundwater and seawater, might affect mechanical property of cemented soil. In this paper, some testing was made about cemented soil curing in erosive chemical conditions. Based on the testing data, the mechanical effects of cemented soil in different environmental conditions were discussed. The results show that the chemical erosion was evident on cemented soil. At the same time, mechanisms of erosion were analyzed. |
