TLDR
In this paper, the trend/rate of settlement of any load on clay can be measured at any time without knowing the past history of load increment, which can be a source of some useful information like quick evaluation of consolidation characteristics, time-compression data of the present, past and future, type and stage of consolidation, drainage conditions, time of increase increment, etc.Abstract:
The trend/rate of settlement of any load on clay can be measured at any time without knowing the past history of load increment. It can be a source of some useful information like quick evaluation of consolidation characteristics, time-compression data of the present, past and future, type and stage of consolidation, drainage conditions, time of load increment, etc. Basic mathematical/graphical properties of vertical, radial, 3D and secondary consolidations are studied from this angle. Two types of 3D consolidations are discussed. First is the combined vertical and radial consolidation with vertical drains. Second is the general 3D consolidation in Cartesian co-ordinates where drainage occurs through all the six phases of a parallelopipe-shaped sample. But the settlement in both cases is allowed in the vertical direction only. It is shown that primary compression after 60% consolidation, with whatever simple or complicated drainage conditions, essentially gives a straight line on a linear plot of settleme...read more

Theoretical equations of vertical and radial consolidation by equating degrees of consolidation by settlement analysis and dissipation of pore pressure
TL;DR: In this paper, a new equation of radial consolidation is derived by equating the above two degrees of consolidation, and the new equations are compared with the existing equations of vertical and radial consolidations.

Equation of 3D consolidation in cartesian coordinates
TL;DR: In this article, the super position of rate of settlement for 2D and 3D consolidation was derived in simple and short manner without any partial differential equations, and the new equations are useful when the soil drains in two or three stratified vertical and horizontal (Z-Y or Z-Y-X) directions, but the settlement is allowed in vertical (Z) direction only.

Consolidation of Fine-Grained Soils by Drain Wells
TL;DR: In this paper, mathematical analyses of drain wells have been used to accelerate the consolidation of fine-grained compressible soils subjected to new loads, but these analyses have only recently become available.
