Sand of well quality is difficult to be supplied for horizontal drain to accelerate consolidation velocity. On the other hand, pre-fabricated board drain (PBD) is recognized as an alternative major material. PBD is generally installed in gridlike manner. However, its conventional drain design manual is insufficient in order to take various materials into consideration. In this paper, two layers horizontal drain model and its numerical treatment by differentiation for computing is presented to promote the PBD horizontal drain design. A consolidation delay is the important issue for the applicability of PBD horizontal drain. The consolidation delay caused by a mat resistance is analytically presented by Yoshikuni. As the PBD horizontal drain is installed in different manner from the Yoshikuni model, a reasonable and compatible mat resistance factor should be constituted for the gridlike fashion. In this paper, a new treatment will be presented considering the similarity of equation with Yoshikuni`s mat resistance factor. After comparing the consolidation delay induced by the presented model with Yoshikuni model, the proposed design procedure for the PBD horizontal drain is investigated.
