弱胶结作用下不同粒径硅质砂物理力学性状试验研究

Study on Physical and Mechanical Properties of Siliceous Sands with Different Particle Sizes under Weak Cementation

砂性土加固过程中,水泥胶结效果对不同粒径砂土渗透性及强度具有重要影响。为进一步了解注浆过程中水泥浆液在砂粒间扩散及胶结效果,采用一维渗流试验对不同粒径硅质砂注浆前、后渗透性及单轴抗压强度性状进行了系统研究与分析。

The cementing effect of cement has an important influence on the permeability and strength of sand soil with different grain sizes in the process of sand consolidation. For further understanding in the process of grouting cement grout diffusion and the effect of cementation between the sand,one dimensional seepage test for different particle size of silica sand permeability before and after grouting and uniaxial compressive strength of character to the research and analysis system.
