一、前言70年代以来,文献[1,2]研究了非达西流对固结过程的影响;并认为在某些粘性土中,孔隙水压降大于起始比降后渗流才能发生。文献[3]虽然给出了有起始比降的固结问题的近似解,但不能计算动边界的位置,不仅如此,该近似解还是用无穷级数表示的。有起始比降的团结问题,实质上是一个有动边界的渗流问题,因此寻求能反映团结过程且计算公式简单的近似解仍然有意义。
I. INTRODUCTION Since the 1970s, the literature [1,2] has studied the influence of non-Darcy flow on the consolidation process; and it is believed that in some cohesive soils, the pore water pressure drop can occur only after the initial ratio drop and seepage. Although [3] gives an approximate solution to the consolidation problem with an initial slope, the position of the dynamic boundary cannot be calculated. Not only that, but the approximate solution is also represented by infinite series. The problem of solidarity with initial slope is essentially a seepage problem with a moving boundary. Therefore, it is still meaningful to seek an approximate solution that can reflect the solidarity process and the calculation formula is simple.
