The invention discloses a permeable environment simulator experimental device and a permeable environment simulator experimental method suitable for a permeable brick. A water storage tank is arranged on the upper part of a machine frame; a flow control valve, an electronic flow meter and a water spraying pipe are arranged on the lower part of the water storage tank; the middle part of the machine frame is provided with a permeable brick bracket groove of which the middle part is provided with a bracket screen which is used for supporting a permeable brick, the upper part is provided with a runoff water guide groove, and the lower part is provided with a permeable water guide groove; the lower part of the machine frame is provided with a runoff water collecting tank positioned below the runoff water guide groove and a permeable water collecting tank positioned below the permeable water guide groove; the lower part of the runoff water collecting tank is provided with a runoff amount weighing sensor; the lower part of the permeable water collecting tank is provided with a permeable amount weighing sensor; and the electronic flow meter, the runoff amount weighing sensor and the permeable amount weighing sensor are connected with a computer. The device and the method can simulate different rainfall environments, and can realize the detection, the computation and the display of thepermeability, a permeability coefficient, the permeable amount and the runoff amount of the permeable brick through the computer; and therefore, the detection for the permeable brick is scientific and reasonable and human factors are ruled out.
