解釋
垂直排水砂井-
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
摘要基於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，並求得常荷載作用下的徑向排水固結解析解。 -
