| Abstract | The main object of the present work is to study One-dimensional consolidation of saturated soft clay with radial pore water pressure dissipation under constant magnitude of constant pressure using central vertical sand drain of different diameters and their maximum and minimum drainage path and geometrical shapes like circular, band, tripod and plus shape keeping same surface area. The optimum diameter and geometry of sand drain is investigated using 'n' values (ratio of zone of influence to the diameter of drain) equal to 11.04, 16.93 and 21.71 using 254mm size modified hydraulically pressurized oedometer.Aim was also to study the efficacy of sand as filler material so as know the rate of development & dissipation nature of pore water for better economy using isochrones. Time - pore water pressure dissipation observations were recorded under different applied stress under long termed duration for all types of drain so as to compute coefficient of consolidation and average degree of consolidation using the theoretical solutions developed by the authors. The results show a fair agreement between measured and predicted values for all shapes and size of drains. Out of all vertical sand drains the circular drain proved to be most optimum one in respects of consolidation characteristics. |
