Embodiment Construction

[0025] Refer to attached picture. The present invention includes an anchor 4 and a test tank 12 for setting a simulated seabed. The simulated seabed includes a gravel drainage layer 1 and seabed clay 2, and the reference number 3 is water. The anchor can adopt a suction anchor model, or a flat anchor model. The test platform is also equipped with:

[0026] 1), the loading fixture 11 arranged above the test tank.

[0027] 2), the vertical power device detachably installed on the loading fixture, the power device can pull or press the anchor, the vertical power device uses a vertical oil cylinder 8, and the reference number 7 is its lower oil inlet , the reference number 9 is its upper oil inlet, the reference number 15 is its spare oil storage tank, the reference number 16 is its oil inlet pipe, the reference number 17 is its oil outlet pipe, and the reference number 18 is the oil pressure controller. When the anchor is a flat anchor model, its installation is completed by p...

The testing platform comprises anchors, testing grooves, a loading fixed frame, a vertical power device, a connecting mechanism, a vertical power device pulling force sensor, a first displacement sensor, an inclinometer, a tension regulator, a pulling cable, a pulling cable guide pulley block, a pulling force direction regulating mechanism, a pulling cable tension measurement sensor, a second displacement sensor, a pulling cable circulating load regulator, a third displacement sensor and a fourth displacement sensor. The invention can realize the model testing research of the bearing capacity characteristics of the novel mooring foundation in deep sea complex static and dynamic loading environments, improves the efficiency of the model testing and the stability of results, and has great promotion and pushing functions on the research of the novel deepwater mooring foundations.

Description

technical field [0001] The invention belongs to the technical field of new indoor model test equipment for deep water mooring. Background technique [0002] In recent years, with the development and utilization of marine resources gradually shifting to the deep sea, the research on new marine foundations suitable for deep-water tensioned mooring systems has attracted more and more attention. Among them, the bearing capacity characteristics of the new mooring foundation under the deep sea complex load environment is the focus of current research at home and abroad and the future development direction. Relevant theoretical research and establishment of numerical models require a large amount of reliable and detailed experimental data to verify and optimize. Compared with the in-situ test, the model test method has the advantages of low cost, easy operation, and less external interference factors, and plays an irreplaceable role in scientific research. At present, many model ...
