A method for testing the bearing characteristics of an anchor foundation under the combined action of scour and a trench
By establishing the constraint relationship between the anchor foundation and the trench and a unified coordinate system in the experiment, the problems of arbitrary parameters and poor comparability in existing experiments were solved, and the actual seabed morphology and the bearing characteristics of the anchor foundation were more realistically reflected and systematically analyzed.

AI Technical Summary
In existing experiments, parameter selection relies on experience and lacks unified constraints, resulting in poor comparability of experimental results and making it difficult to systematically analyze the impact of the combined effects of scouring and trenching on the bearing characteristics of anchored foundations.
By establishing constraints on the dimensions of the anchorage foundation, the geometric parameters of the trench, and their relative positions, and by calculating the outer edge dimensions of the test area, the maximum dimensional combination of the anchorage foundation and the trench is determined. Different working conditions are constructed under a unified coordinate system to achieve unified control and coordination of parameters.
The test conditions were improved in terms of engineering rationality and comparability. The influence of trench position changes on the bearing characteristics of anchor foundations was systematically analyzed, and the repeatability and stability of the test results were enhanced.
