Gravel Drains have many advantages in counter-measures of liquefaction. But there are many uncertaion points in this method because liquefaction-mechanism is complicated. And there are many factors which control antiliquefaction effect. Therefore reliable plan methods have not yet been established and only a few examples of construction are seen. The purpose of this study is to solve many questions in the antiliquefaction mechanism of Gravel Drains and to find the numerical value concerning the original ground for the suitable plan method. In most plan methods of Gravel Drains which have been used for construction so far Gravelpile-permeablity-coefficient is large enough. The result of this study shows that the plan method in consideration of Gravelpile-permeability-coefficient is possible at least and it is suitable to use this method for Gravel Drains.
