What is primarily tested in pile foundation inspection?

1. Vertical and horizontal bearing capacity testing of various piles, abutments, and pile walls, including single pile and group pile bearing capacity testing.

2. Detection of the bearing capacity and deformation characteristics of the bottom cushion layer.

3. Integrity testing for various piles, abutments, and pile wall structures.

4. Consideration for the detection of the combined action of piles and soil or the load distribution ratio of piles and soil in composite foundations; as well as the detection of pile and soil stress-strain.

5. Environmental impact assessments during construction (e.g., vibration, noise, soil deformation)

6. Other inspections under special conditions or during accident handling.
