The invention provides a seabed pore water pressure observation device based on internal solitary waves and a working method thereof. The seabed pore water pressure observation device comprises a penetration power system, an observation system and a stabilization system. The penetration power system is composed of a recovery ring, a buoy, a Kevlar cable, a limiting cylinder, a cubic limiting block, a control unit, an annular control cabin, a heavy block and an annular iron block. The observation system is composed of a first pore pressure feeler lever, a pore pressure feeler lever storage unit, a circular-truncated-cone-shaped limiting block, a one-way limiting device, a horizontal supporting rod, a second pore pressure feeler lever, a first penetration conical tip, a pore pressure sensor,a second penetration conical tip and an annular lantern ring.According to the invention, the penetration requirement of the in-situ observation device for seabed pore pressure under the action of internal solitary waves is met; the penetration effect is guaranteed, the energy of the internal solitary waves can be used as a resource, the design and operation cost of the device is reduced, and therequirement for real-time and in-situ observation of pore water pressure changes in a seabed under the action of the internal solitary waves can be met.
