石灰改善土与石灰稳定土在施工要求上没有什么大的区别,一般不引起施工管理者的重视。在实际施工过程中,由于其土质的特殊性、灰剂量小、施工难度较大和不易成型等特点,常常遇到各种质量问题并产生病害,如不采取一些有效的措施加以控制,往往难以达到设计要求。结合工程实例,对石灰改善土施工过程中影响压实与强度的因素以及常见的病害产生机理,进行了认真而又系统的分析,同时提出了一些有效措施,对控制石灰改善土施工的质量具有现实指导意义。
Lime to improve the stability of soil and lime soil in the construction requirements is no big difference, generally do not cause construction managers attention. In the actual construction process, due to its particularity of soil quality, small amount of ash, difficult construction and difficult to shape, it often encounters various quality problems and causes diseases. If it is not controlled by some effective measures, it is often difficult to achieve Design requirements. Combining with the engineering examples, the factors influencing the compaction and strength during limestone construction and the common mechanism of disease generation were carefully and systematically analyzed. At the same time, some effective measures were proposed to improve the quality of soil construction by lime control Practical guidance.
