水泥土加固体的劣化特性研究进展

Research Progress on Cement Stabilized Soil Degradation Characteristics

水泥土加固体因其优秀的抗压强度、就地取材成本低廉、施工方法简便等优点成为改良软土地基最为常见的方法。但因环境污染或地下土层本身具有腐蚀性等原因,水泥土加固体劣化问题受到人们重视。为此对水泥土加固体强度增长机理、劣化机理、影响劣化深度的因素、渗透性变化等方面的研究进行归纳总结,对有关水泥土加固体劣化问题研究不足之处进行讨论,为水泥土加固体未来研究方向提出展望。

Cement stabilized soil have become the most common method for improving soft soil foundation in China due to its excellent compressive strength,low cost of local materials and simple construction methods.However,the problem of deterioration of cement stabilized soil has attracted attention due to environmental pollution or the corrosive nature of the subterranean soil itself.The research on the strength growth mechanism,deterioration mechanism,factors affecting the depth of deterioration and permeability change of cement soil were summarized.In addition,the insufficiency of the research on cement soil solidification degradation were discussed,and the future of cement soil solidification was put forward.
