Embodiment 1

[0043] Such as figure 1 , figure 2 , image 3 Shown is a three-way cyclic load loading device that can realize the function of soil consolidation. The device includes a pressurization consolidation unit and a three-way cyclic load loading unit arranged on the pressurization consolidation unit. The pressurization consolidation unit It includes a box body 1, a pressurization power mechanism arranged inside the box body 1, and a pressurization mechanism connected with the pressurization power mechanism. The three-way cyclic load loading unit includes a support frame set on the box body 1 and a The three-way load loading mechanism on the

[0044] Such as Figure 4 As shown, the pressurizing power mechanism includes 4 tension jacks 2 evenly arranged at the bottom of the box body 1 and a dowel 3 connected to the piston transmission of the tension jack 2, the pressurizing mechanism is arranged on the top of the dowel 3, and Dowel bar 3 is fixedly connected. The pressurizing mec...

Abstract

The invention relates to a three-way cyclic load loading device capable of realizing a soil consolidation function. The device comprises a pressure consolidation unit and a three-way cyclic load loading unit arranged on the pressure consolidation unit, wherein the pressurization consolidation unit comprises a box body, a pressurization power mechanism arranged in the box body and a pressurizationmechanism in transmission connection with the pressurization power mechanism, and the three-way cyclic load loading unit comprises a supporting frame arranged on the box body and a three-way load loading mechanism arranged on the supporting frame. Compared with the prior art, the invention has the advantages that the pressure consolidation device is firstly utilized to simulate an on-site ground stress environment to realize the pressure consolidation of a soil body, and then the three-way cyclic load loading unit is utilized to apply three-way cyclic load to a basic structure model in the soil body to simulate the action of a foundation on the three-way cyclic load for a long time, so that the reliability of a test result is improved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering structure tests, and relates to a three-way cyclic load loading device capable of realizing the soil consolidation function. Background technique [0002] With the development of technology, the society's demand for energy is increasing day by day, coupled with the gradual awakening of people's awareness of environmental protection, the traditional energy with high pollution and high consumption has gradually been unable to meet the development needs of society, so there is an urgent need to develop new clean energy. There is a huge amount of wind energy stored in the ocean. If it is used, it can greatly alleviate the energy demand of social development. In the past two decades, offshore wind turbines have developed rapidly in Europe, America and other countries, and have entered the stage of practical application in my country. [0003] However, when the wind turbine is in operation, d...
