Summary:The utility model discloses a novel ocean soil full-flow penetration system, and belongs to the field of civil engineering. The elliptical section probe with the axial length ratio of 0.4 is adopted to further reduce the test error caused by the resistance coefficient of the probe, and the linear relationship among the resistance coefficient of the probe, the resistance coefficient error and the axial length ratio is given; the fiber bragg grating is arranged on the outer wall of the feeler lever to replace a traditional pressure sensor, and the end resistance and the lateral friction resistance of the probe are tested in the cyclic penetration process; based on a full flow theory, a limit analysis method of soil plasticity mechanics is utilized, an algorithm of soil mass undrained shear strength is given theoretically, and a corresponding algorithm is given in combination with the geometric form ratio of a probe to a feeler lever; arranging a pore pressure sensor on the elliptical probe, and testing the pore
