geostatic curve

Based on the equal strain consolidation model of sand drain , and neglecting the well resistance and the vertical drainage consolidation , a layered model for the nonlinear consolidation of sand drain , which accounts for the geostatic pressure varying along depth and the relationship between the average viod ratio and the logarithm of average effective stress , is presented 摘要基于砂井等應變固結模型,考慮初始有效應力沿深度變化,忽略井阻和豎向排水固結的影響,應用平均孔隙比與平均有效應力的對數關系,建立砂井非線性徑向排水固結的分層計算模型,并求得常荷載作用下的徑向排水固結解析解。

The treatment for simplity that the mean value of the geostatic pressure is adopted could result in a smaller computed value of settlement but a larger one of average radial consolidation degree than the actual 如把整個厚度范圍內自重應力取為平均值,將使計算的沉降量偏小,徑向平均固結度偏大。

It is concluded that the average degree of radial consolidation for a given soil layer increases with its buried depth since the geostatic pressure increases with the lattar 結果表明,因自重應力隨深度增加,土層徑向排水平均固結度隨其埋深而增大。
