| 摘 要： | 在Terzaghi一维固结理论的基础上,提出了一个从透水到不透水的双面不对称连续排水边界条件,建立了广义Terzaghi固结理论,并给出其解答.对其解答进行分析发现:修正后的固结方程的边界条件能严格满足其初始条件;通过变化边界条件中的参数,可以得到包括Terzaghi一维固结理论解答在内的连续解,从而弥补了Terzag...

| Abstract: | The problems of traditional one-dimensional consolidation theory are analyzed.An asymmetric continuous drainage boundary which has two surfaces from pervious to impervious is put forward.The solutions based on these conditions are given.The boundary conditions of the modified consolidation equation meet their initial conditions strictly.The degradation solutions show that the equation is well-posed,continuous and has its physical meanings.The studies on terms in series of calculating solutions show that onl... |
