| 摘 要： | 研究了一维向上渗流作用下双层地基有效应力的计算问题，推导了有效应力的计算公式，讨论了有效应力性状。渗流作用下土层有效应力由两部分组成：一部分是自重有效应力，由重力引起的，体现了静水压力的影响；另一部分是渗透有效应力，是由土层水头差产生的，体现超静水压力的影响，文后给出了实例计算。

| Abstract: | A analytical solution is given to the problem of calculation of effective stress for a double layered ground under one dimension upward seepage. The formulas for computing the effective stress are derived. Based on the formulas, the characteristics of effective stress are discussed. The effective stress for a double layered ground under one dimension upward seepage is divided into two parts of both effective stress of weight and effective stress of seepage, the former embodying the effect of hydrostatical pressure is brought about by the weight, and the latter embodying the effect of super hydrostatical pressure is given rise to by the seepage.To illustrate the analytical procedure an example is given in the end of the paper. |
