【摘要】：为研究不同土体中水泥-水玻璃浆液扩散规律,基于浆液劈裂土体形成的裂缝形状和宾汉流体在平板裂缝中的流变方程,推导出不同土体中水泥-水玻璃浆液黏度、流量、注浆压力差、浆液扩散距离的计算公式,计算分析不同土体中水泥-水玻璃浆液的黏度、注浆压力以及裂隙高度对浆液扩散距离的影响。研究结果表明:浆液扩散距离随浆液黏度的增大呈非线性减小,随注浆压力的增大呈非线性增大,裂隙高度增大使浆液扩散距离迅速增大;通过注浆后工程现场取芯试验对计算结果进行分析,验证了不同土体中浆液扩散距离和劈裂缝高度的关系。
[Abstract]:In order to study the diffusion law of cement-water glass slurry in different soil mass, the viscosity and flow rate of cement-water glass slurry in different soil were deduced based on the crack shape formed by the slurry splitting soil and the rheological equation of Bingham fluid in the slab crack. The difference of grouting pressure and the calculating formula of slurry diffusion distance are calculated and analyzed. The influence of the viscosity of cement-water glass slurry in different soil mass, grouting pressure and crack height on the slurry diffusion distance is analyzed. The results show that the diffusion distance of the slurry decreases nonlinear with the increase of the viscosity of the slurry, increases with the increase of the grouting pressure, and increases with the increase of the fracture height, and the diffusion distance of the slurry increases rapidly with the increase of the viscosity of the slurry. The calculation results were analyzed by field coring test after grouting, and the relationship between the dispersion distance of slurry and the height of split crack in different soil was verified.
