Study on Permeation and Diffusion Mechanism of Viscous Time-varying Bingham Fluid in Sandy Formation
Due to the existence of a large number of porous pipes in sandy strata,the diameters of the pipes are not equal,and the rheology of the grout is related not only to the water-cement ratio,but also to admixture and time,etc.Initial viscosity cannot be used as the only index to judge rheology.In order to make the diffusion mechanism of grouting materials more in line with the actual diffusion situation of sandy strata.In this paper,the cylindrical diffusion mechanism of Bingham fluid with viscosimetric time-varying in non-uniform tube sets is studied,and the diffusion mechanism is applied to the study of a new grouting material mixed with industrial waste slag.Finally,the theoretical diffusion range of the new grouting material in sandy stratum is obtained,which provides a reference for the application of this grouting material in practical engineering.
