透明土中孔隙液体折射率、黏度系数与稳定性
Refractive index, viscosity coefficient and stability of pore fluids in transparent soil
摘要
Abstract
In order to verify the feasibility and stability of pore fluids used to manufacture transparent soil and provide references for relevant transparent soil model tests, the relationships of the refractive index and viscosity coefficient with the mass ratio of the solution were determined for four water-based inorganic solutions ( calcium bromide, potassium pyrophosphate, potassium phosphate, and magnesium chloride hexahydrate ) and one oil-based organic solution ( the mixture of mineral oil No. 15 and dodecane). The calcium bromide solution and the mixture of mineral oil No. 15 and dodecane are two typical pore fluids in model tests. Experiments on the influence of the two pore fluids on the size deformation and tensile strength of latex membrane and solid granular particles were carried out. The results show that the refractive indices of the water-based inorganic solutions linearly increase with the mass ratio of the solution, and the viscosity coefficients nonlinearly increase with the mass ratio. Under the same conditions, the length change rates of the latex membranes after being immersed in the calcium bromide solution and the mixture of mineral oil No. 15 and dodecane are 0. 47% and 37. 81%, respectively, their width change rates are-1. 09% and 40. 50%, respectively, and their tensile strengths decrease by 13. 5% and 89. 4%, respectively. The effect of the pore fluids on the fused silica sand is smaller than that on the amorphous silica. The effect of the mixture of mineral oil No. 15 and dodecane on the solid particles is basically the same as that of the calcium bromide solution.关键词
