The invention discloses a device for testing the clogging characteristic of a gravel pile drainage anti-liquefaction channel indoors. The device comprises: a soil sample chamber which is of a transparent cylinder structure with a closed bottom, wherein a side wall of the soil sample chamber is provided with scales, so that the moving clogging condition of a soil sample in the soil sample chamber can be conveniently observed; a vertical loading system which comprises a counter-force frame and a pressurizing mechanism, wherein the soil sample chamber is arranged in the counter-force frame, and the pressurizing mechanism is arranged on the counter-force frame and used for applying vertical pressure to the soil sample in the soil sample chamber; a pore pressure loading system which is communicated with a water outlet formed in the top of the soil sample chamber and a water inlet formed in the bottom of the soil sample chamber, and is used for providing different pore pressures when the soil sample chamber is subj
