The invention discloses a consolidometer for measuring pore pressure, which comprises a soil sample storage device, a pressing head, a displacement sensor and a measuring control system, wherein a to-be-detected soil sample is filled in the soil sample storage device; a plurality of soil pressure boxes are arranged on a same plane of the soil sample; a plurality of soil pressure boxes are arranged along the vertical direction of the soil sample; the pressing head is arranged corresponding to the soil sample storage device and is used for applying pressure to the soil sample; the displacement sensor is arranged on the pressing head and is used for measuring the deformation of the soil sample; the measuring control system is in data connection with the soil pressure boxes, the lifting mechanism and the displacement sensor. The consolidometer for measuring pore pressure, provided by the invention, can automatically pressurize through a corresponding measuring control system procedure and can greatly increase the working efficiency. The consolidometer can gradually load pressure. Data is collected for the sedimentation displacement through the displacement sensor, so that the error can be reduced.
