摘要
本文根据动荷载下饱和砂土中孔压产生的不同原因,将孔压区分为应力孔压,结构孔压和传递孔压,并将它们和土物态的变化相联系,阐明了孔压发展周期形态变化的机理,提出了各类孔压的计算模型以及模型中有关参数的确定方法,为进行瞬态孔压的计算提出了新的途径。
In this paper the pore water pressure in saturated sand under cyclic loading are classified into stress pore water pressure, structure pore water pressure and transmission pore water pressure according to their resources. Based on their connections with the change of physical states of soil, the mechanism of the form of pore water pressure change in any loading cycle is interpreted, the calculating models and the method of determining the corresponding parameters are suggested. Lastly, a new approach of transient pore water pressure calculation are presented.
