摘要
混合物理论采用最经典的力学假设,对土体的沉降与固结特性做了更为一般的运用。在其基础上,基于各组份的平衡法则及其物理量的守恒原理,结合经典的单颗粒物体在流体中运行规律,得出物质在静水沉降过程一般运动规律。对悬浮液与液体分界面沉降规律给出一个计算公式,结果表明悬浮液以激波形式发展运动。
Based on the classic assumptions, the mixture theory is applied in the analysis of sedimentation and consolidation of soil. Combining classic movement laws of a single particle in the fluid,the paper got normal movement laws of material during the quiescent sedimentation. The paper also got a formula of subsidence of the interface between suspensions and fluid. It＇ s shown that the movement of suspensions is similar to that of shock-wave.
