本文将Terzaghi二维固结理论与震动孔隙水压力增长模式相耦合,提出了一类饱和砂层震动孔隙水压力的二维扩散解析理论。文中首先给出了计算饱和砂层中震动孔隙水压力生长与扩散的理论解,并讨论了几种不同起始孔压场分布情况下解的简化表达形式;其次,证明了该解析解是适定的。因为所采用的震动孔隙水压力增长模式是一个随时间和土的物理力学参量而变化的一般函数,其具体函数形式可根据实际条件来合理选定,这使得所给出的理论解带有普遍性。
In this paper, the two-dimensional consolidation theory of Terzaghi is coupled with the growth model of vibration pore water pressure, and a two-dimensional diffusion analysis theory for the pore water pressure of saturated sand is proposed. In this paper, the theoretical solution for calculating the growth and diffusion of water pressure in the vibratory pores in a saturated sand layer is first presented. The simplified expressions of solutions for the distribution of pressure fields in several different initial pores are discussed. Secondly, it is proved that the analytical solution is suitable. Definitely. Because the vibration pore water pressure growth mode adopted is a general function that changes with time and soil physical and mechanical parameters, its specific function form can be reasonably selected according to actual conditions, which makes the given theoretical solution universal Sex.
