基于不对称连续排水边界的太沙基一维固结方程及其解答
Terzaghi's one-dimensional consolidation equation and its solution based on asymmetric continuous drainage boundary
摘要
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 only one term in series in cakulation process can meet the precision requirement well for a larger consolidation degree, and that more terms in series can meet the precision requirement when the consolidation degree is smaller. So the results calculated by the equation can extend to engineering application conveniently.关键词
