The method comprises the steps of A, completing the azimuth adjustment and the soil filling of a rigid retaining wall inside a box; B, injecting water into the box through a water inlet pipe by means of a water pump; C, infiltrate the water into the soil through the porous plate of the water inlet pipe in the box; D, blocking the water inlet pipe and an exhaust pipe, and standing; E, controlling the movement of the rigid retaining wall through upper and lower jacks; F, acquiring the pressure of the pore water through a pore pressure probe to obtain the result of the active soil pressure and the passive soil pressure under the seepage effect. A test device is composed of a box, an upper sliding block, a lower sliding block, an upper sliding groove, a lower sliding groove, an upper jack, a lower jack, a rigid retaining wall, a vertical bearing plate, a flexible loading water bag, a film type pressure sensor, a pore pressure probe and a displacement sensor. The device is convenient in operation, high in efficiency and energy-saving. Meanwhile, the requirements of testing active and passive soil pressures under the seepage effect are met.
