【摘要】 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 ,分析了各种因素对施工质量的影响。结果发现 ,在施工过程中 ,灰土地基的土体含水量、含灰量、虚铺厚度、碾压过程及碾压间隔历时等都对施工质量产生一定的影响。研究在确定灰土的最优含水量和最佳含灰量的基础上 ,提出了保证黄土灰土地基施工质量的控制系统以及为保证黄土灰土地基质量而应采取的有效措施。更多还原

【Abstract】 Test is carried out to study the physical and mechanical property of lime loess soil and the significance of quality control during the construction of lime loess foundations.The effects of various factors are analyzed and the result indicates:the water content of soil,the ash content,the lime loess virtual paving depth,the process of roller compaction and the interval duration of roller compaction in the construction have certain effects on the construction quality.The lime loess optimum water content and optimum ash content are determined.Based on that,the quality control system and the efficient measure to keep the quality of lime loess foundation are presented.更多还原
