Abstract

The invention discloses a power penetration flat-plate anchor test device for a supergravity centrifuge. The test device consists of five parts: the test model box, the magnetic induction positioning system, the anchor release device, the load measurement device and the dynamic penetration plate anchor; there is a test foundation in the test model box, and a The slide rail of the model box is equipped with an anchor release device and a loading measurement device; the magnetic induction positioning system is installed on the anchor plate of the dynamic penetration flat plate and the test model box. The invention solves the problem that it is difficult to obtain the motion information of the anchor body due to the invisibility of the soil, and can accurately and effectively perform the power penetration plate anchor test of the supergravity centrifuge.

Description

technical field [0001] The invention relates to a test device and method for a flat anchor in a supergravity centrifuge, in particular to a test device and method for a power penetration flat anchor used in a supergravity centrifuge. Background technique [0002] my country has a sea area of ​​3 million square kilometers, rich in oil and gas, wind power, tidal energy and other energy reserves. At present, offshore oil production has begun to take shape. The proposal of the "marine power strategy" has promoted the exploitation of oil and gas resources in my country to gradually enter the deep water area of ​​the South China Sea, which also puts forward higher requirements for the deep water mooring system of offshore oil production platforms. As the water depth continues to increase, offshore oil production platforms have transformed from traditional fixed platforms to new structures such as tension leg platforms (TLPs) and floating production, storage and offloading units (F...
