摘要
通过水泥加固土的一系列室内试验和现场测试以及水泥土硬化机理中水的作用研究,分析影响水泥土性能的因素并着重分析含水量对水泥加固土性能的影响,揭示了上海软土地区综合含水量是影响水泥土加固效果的关键因素,针对上海饱和软粘土地区水泥土加固工程,提出在不增加水泥用量的情况下,通过改进施工工艺技术,控制综合含水量的方法来提高水泥土加固效果,从而在深基坑等工程应用中充分发挥坑内加固水泥土控制变形的作用及工程效益。
Through a series of laboratory and in - situ tests on the cement treated soil and research on the effect of water during cement treated soil hardening, the author analyzes the factors which influence the mechanical properties of cement treated soil and pays more attention to the effect of water content, and reveals that the comprehensive water content plays a key role during cement treated soil consolidating. The conclusion can be drawn that, to the saturated soft clay of Shanghai, the strength of cement treated soil can be increased by only improving the construction procedure and controlling comprehensive water content, but without adding the dosage of cement. This conclusion can make the soil treatment work more effectively and be more economical.
