摘要
雨水、洪水渗透时河堤的稳定性问题是一个牵扯到饱和- 非饱和状态水分的渗透和水分变化时非饱和土的强度低下的复杂的工学问题。研究雨水、洪水渗透时河堤内部的水分移动以及土的力学性质变化有利于搞清河堤的破坏机理,以便于合理地进行河堤加固并能够进行有效的抗洪抢险工作。
Upon the infiltration of rain or flood, change of the stability of the river embankment is a very complicated process, that involves water movement in saturated-unsaturated states and the decrease in the strength of the unsaturated soil. Study of the water movement and the change of the soil mechanical properties would lead to the understanding of the dike collapse mechanism, thus would be helpful in reinforcing embankment and effective preventing flood damage. In this paper we analyzed and stated the dike collapse mechanism from two full-scale embankment infiltrating tests.
