Abstract: An integrated seabed geological sampling/testing system is developed for marine geological survey. The system has the functions of static pressure penetration sampling, vibration penetration sampling and in-situ test. The static pressure penetration sampling function adopts the fuzzy control algorithm to control the speed and torque of the friction wheel to ensure the synchronism of the two friction wheels. The double friction wheel holds the sampling pipe to penetrate into the stratum for sampling, which has high fidelity. In the sand layer, the sand can be liquefied and sampled by the function of vibration penetration sampling. In situ testing, multi-functional static cone penetration is used to obtain the mechanical properties, resistivity and geothermal gradient of the seabed directly.

Keywords: geological survey; seabed type; static pressure sampling; vibration sampling; static cone penetration.
