Incessant rainfalls in unsaturated soil raises pore water pressure and drops shear stress. Controlling pore water pressure in unsaturated soil prevents pressure increase and leads to slope stability. Laboratory experiment of pore water absorption in soil tank has been conducted for pore pressure decrease in soil slope under artifical rainfall supplied in varying rainfall indensities. Soil slope failure triggers the deepening of the wetting front to critical depth accompanied by decrease in matric suction induced by water infilteration. This paper addresses an experimental design for absorption pipe to prevent pore pressure increase in unsaturated soil slope from heavy rain. It is expected that absorption pipe will be widely used in unsaturated soil slope to strengthen slope stability.
