摘要 在一维固结理论的基础上,提出一个从透水到不透水的双面不对称连续排水边界条件,建立广义固结边界条件,并给出边界下2类主要一维固结理论的解答.对解答进行分析发现:修正后固结方程的边界条件不但能严格满足其初始条件,并且其退化结果表明方程是适定的,所得的解是连续的,具有物理意义.文中边界条件可以更加精确地预测饱和黏性土体的固结速率. A asymmetric continuous drainage boundary with two surfaces from pervious to impervious was put forward.The answers based on the conditions were given.The boundary conditions of the modified consolidation equation meet their initial conditions.The degradation answers with continuous and physical meaning show that the equation is suitable.The new boundary of the consolidation function can estimate the consolidation rate of the saturated clayey soil.
