Test device for simulating multidirectional coupling cyclic loading of anchor pile system

Abstract

The invention relates to a test device for simulating multidirectional coupling cyclic loading of an anchor pile system. The test device comprises a model pile buried in a model box, a reaction frame,a static balance unit, a power circulation unit, a diameter guide rail, a balance weight pull wire, a horizontal loading pull wire and an oblique loading pull wire. The balance weight pull wire is connected with the power circulation unit to balance the gravity of the power circulation unit and is connected with the model pile to provide a vertical static load or an oblique static load for the model pile, the static balance unit is also connected with the model pile through a horizontal loading pull wire to provide a horizontal load for the model pile, and the power circulation unit is connected with the model pile through the oblique loading pull wire to provide circulation loads for the model pile. Compared with the prior art, the test device has the advantages of wide application range, high simulation precision, small size and the like.

Description

technical field [0001] The invention relates to a static and dynamic cyclic loading device in a model test, in particular to a test device for simulating multidirectional coupled cyclic loading of an anchor pile system. Background technique [0002] In recent years, in the face of increasingly severe environmental and resource problems, countries around the world are seeking safer, cleaner and renewable energy. In my country's energy consumption, traditional fossil energy accounts for a large proportion, with low energy utilization efficiency, large waste and pollution, so it is particularly urgent to develop new clean energy. In the past two decades, wind turbines have developed rapidly all over the world. China has become the country with the largest installed wind power capacity in the world. The construction of offshore wind power projects can make full use of abundant wind energy resources. Wind power projects have developed from land to shallow seas, and from shallow ...

Problems solved by technology

Referring to the foundation forms of fixed offshore wind turbines and offshore oil exploration platforms, LeBlanc et al. (2010) and Muhanmad et al. (2016) developed two different long-term horizontal cyclic loading devices for single piles, and Yeong-Hoon et al. (2017) developed a suction bucket The vertical long-term vertical cyclic loading equipment of the mooring foundation, but the above equipment can only be cyclically loaded in a single horizontal or vertical direction. The anchor pile foundation bears the coupled cyclic load of vertical buoyancy and horizontal wave force, and loading in a single direction cannot Realistically simulate the stress of the foundation in the marine environment

Moreover, the two types of devices can only carry out specific tests, which have poor versatility and narrow scope of application.
