| 摘 要： | 考虑渗流力的作用，对太沙基一维固结理论进行了修正，给出了向上及向下渗流时固结度的表达式，并分析了固结过程中渗流应力的变化规律。结果表明：渗流力对固结度的影响较大，特别是在时间因素Tv=0.1附近，是否考虑渗流力的影响将导致固结度的差值达30 %，因而渗流力对固结度的影响是不可忽略的。

| Abstract: | Terzaghi's one-dimensional consolidation theory is modified by considering seepage force, the consolidation equations under both upward and downward seepage are derived and the distribution of the seepage stress during consolidation is also analyzed.It is concluded that the seepage force affects on the consolidation degree obviously, especially when Tv is about 0.1, the values of the consolidation degree considering the seepage force or not will have the difference of 30 %. The author believes that the seepage force cannot be neglected. |
