黄土灰土地基的质量控制系统试验研究

对黄土灰土的物理力学性质和黄土灰土地基施工过程中的质量控制要点进行了试验研究。分析了各种因素的影响程度和影响结果 ,发现灰土不但有最优含水量而且有最佳含灰量问题。同时在施工过程中灰土地基的虚铺厚度、碾压过程及碾压间隔时间等都对施工质量产生一定的影响。

Test Study on Quality Control System of Loess and Lime Soil Foundation

In this article,authors study physical and dynamic features of loess and lime soil and key points of quality control in construction of loess and lime soil foundation.They also analyze the degree and effect of influence of many factors,and find that lime soil has not only the optimal moisture content but also the optimal lime content and that the first spread thickness,rolling process and interval etc.of lime soil foundation all can influence its construction quality.They also provide the control system and effective measures that should be used to ensure the construction quality of loess and lime soil foundation.
