The present invention discloses a second-generation in-situ test device for strength of a shallow water sediment, including a workboat and a static cone penetration test unit carried by the workboat, where the static cone penetration unit includes a mounting frame, a penetration unit, a control cabin and a hydraulic unit; the penetration unit and the hydraulic unit are both electrically connected to the control cabin. In this solution, the workboat is used to carry the test equipment, and the static cone penetration test unit is carried on the workboat with a special structure. Based on a double-cable lifting frame, the equipment is launched and recovered through a moon pool in the center of a hull. This significantly improves the efficiency and safety of the sediment strength test operation in a shallow water environment.

A device for measuring ground penetration resistance that can perform this type of measurements with a hydrostatically compensated tip. Measurements of penetration resistance use a hydraulic compensated cone, which addresses the issue of very soft sediments at high water depths. The cone includes a floating tip, a body, a housing and a sleeve. Low viscosity oil fills the internal cavity between the tip and the core. A differential pressure transducer located at the top of the cone body determines the difference between the insertion related pressure and the background water pressure. This system compensates for this pressure difference using the pore fluid during insertion instead of the water column, which results in greater accuracy.

The present invention provides a lateral and continuous measurement method for soil parameters in a soft soil field. The method mainly comprises the following measurement steps: arranging soil strength measuring apparatuses at the front end of a towing apparatus; arranging soil strain softening relationship measuring apparatuses at the bottom end of the towing apparatus; and measuring interface friction parameters between the soil and a structure. The towing apparatus actively or passively moves in a soft soil layer to ensure that the towing apparatus partially penetrates into the to-be-measured soil layer during movement; and the penetration depth of the towing apparatus is controlled by adjusting counterweight above the towing apparatus and a towing angle.
