Sand of well quality is difficult to be supplied for horizontal drain to accelerate consolidationvelocity. On the other hand, pre-fabricated drain is recognized as the alternative major material.However the conventional drain design manual is insufficient in order to take the variousmaterials into consideration. In this paper, two layers horizontal drain model and its discretizationtreatment by differentiation for computing is presented to promote the horizontal drain design.After comparing the consolidation delay induced by the presented model with Yosikuni.s matresistance concept, and confirming approximation, the design procedure for horizontal drainusing pre-fabricated drain is presented for reduction of consolidation delay.
