Abstract

The invention discloses a test system for simulating the multi-field coupling effect of an offshore wind power rock-socketed pile. The test system comprises a water tank body, the offshore wind powerrock-socketed pile is arranged in the water tank body, the offshore wind power rock-socketed pile is arranged in a rock-soil test box, and the rock-soil test box is arranged on an earthquake simulation system; a turning wind field simulation system is arranged on one side of the offshore wind power rock-socketed pile and can provide a wind field with 180 DEG spatial change; and a wave generation system is mounted in the water tank body, a water supply and drainage system is installed on the side face of the water tank body, and a flow generation system is arranged at the bottom of the water tank body. Simulation of all loads can be realized, 180 DEG real-time conversion simulation of the typhoon wind direction can be realized, and cooperative work among the water tank, the vibration tableand the rock-soil test box can be realized.

Description

technical field [0001] The invention relates to the technical field of test equipment for construction, in particular to a test system for simulating the multi-field coupling effect of offshore wind power rock-socketed piles. Background technique [0002] Under extreme sea conditions, the dynamic load transfer at the pile-soil interface is very complex, with strong typhoon intensity, high turbulence, and significant spatio-temporal variability; typhoons and the extreme waves induced by them act on the piles horizontally and directly on the seabed, causing Additional compressive stress and excess static pore pressure; the seabed will also produce excess static pore pressure under earthquake action, and there will be nonlinear dynamic coupling with the pile foundation; secondly, the water flow in the marine environment also has an important impact on rock-socketed piles. The dynamic response characteristics of rock-socketed piles under the coupling of these load effects have n...
