【摘要】 水玻璃类浆液作为化学灌浆材料,其粘度在随时间变化,因此浆液在砂土中的渗流过程较复杂。首先在达西定律的基础上推导出化学浆液在砂土中的渗流公式,然后采用品氏毛细管粘度计对浆液的粘度进行测定,通过曲线拟合回归总结出浆液粘度随时间变化规律,最终得出浆液在砂土中的渗流规律。更多还原

【Abstract】 When water glass seriflux as chemistry injection material, its kinetic viscosity is varying with time, so the process of seriflux permeating in the sand is complicated. By derivation according to Darcy’s law, the transfusion formula of chemical grouting in the sand was achieved. And then, the capillary viscosimeter was adapted to measurement the viscosity of seriflux. Finally, the change law of seriflux kinetic viscosity varying with time by fitting curve was deduced.更多还原
