摘要
软土渗流过程中,由于其颗粒微小,导致结合水层较厚,结合水的粘滞性和抗剪性能对孔隙水渗流起着显著的阻碍作用.软土圆孔微观渗流模型从微细观层面综合考虑结合水的粘滞性、抗剪性能、土颗粒表面电势、导电率、离子浓度及其电价和孔隙直径等参数对渗流特性的影响,其计算结果与实验数据吻合度高,对于软土工程的渗流计算及工程借鉴具有重大意义.
In the process of soft soil seepage, the viscosity and shear performance of bound water have a great hindering effect. The soft soil circle hole microstructure seepage model considers the effects of the viscosity and shear performance of bound water, the surface electric potential of soil particles, the conductivity, the concen-tration and electric field of ions. The calculation results and the experimental results have a goodness of fit. The theory of circle hole seepage has great significance in the soft soil seepage engineering.
