In this study, the complex drainage effect test had been conducted to estimate drainage capacity of each drain board. It is possible to embody the situation that a drain board is pressurized in the ground by conducting the complex drainage effect test. Drain boards that used in this test were normal PBD, X-typed PBD, SDD, PCD and Fiber Drain. Drainage capacities of all drain boards tend to decrease as confining pressure increases.
