Abstract

The invention relates to a static cone penetration system suitable for a shallow sea area. The static cone penetration system comprises a suction cylinder counter-force device; the suction cylinder counter-force device is fixedly connected with a loading device with a shipborne control system, and the loading device is connected with a static penetrometer; the suction cylinder counter-force devicecomprises a suction cylinder with an opening in the lower end, and the suction cylinder is connected with a vacuum pump through a vacuum pump pipe; the static penetrometer comprises a penetration rodconnected with the loading device, the lower end of the penetration rod is connected with a multifunctional static cone penetration probe, and the multifunctional static cone penetration probe is connected with a static cone penetration recorder. The cone penetration system provided by the invention is small in balance weight, low in requirements for a shipborne crane, simple and direct in operation and low in operation cost; and meanwhile, not only is the measurement precision of a foreign static penetrometer kept, but also the problems that an implementing standard way used in a shallow water area is low in precision and a platform type CPT (Cone Penetration Test) is complex in operation process and poor in stability are overcome.

Description

technical field [0001] The invention belongs to the field of in-situ testing of shallow sea geotechnical engineering, and particularly relates to a static penetration system suitable for shallow sea areas and an application method thereof. Background technique [0002] Cone Penetration Test (CPT for short) is to penetrate the probe into the soil at a uniform speed (2cm / s), record the data, and then combine the indoor geotechnical test to comprehensively evaluate the soil quality and soil layer distribution. The in-situ test method has the advantages of good data continuity and reproducibility, and the operation saves time and effort. In geotechnical engineering investigation, static penetration is a very important method. It has outstanding advantages in excavating stratum distribution, measuring geotechnical properties, and determining foundation bearing capacity. It can also be used in conjunction with laboratory tests. With the rapid development of ocean development, the...
