The paper introduced the pile test in advance of a large engineering in Caofeidian. By the analysis on vertical bearing capacity test, internal force of pile test, low strain dynamic testing, ultrasonic testing and horizontal bearing capacity test of post grouting bored-grouting pile, 3-branch bidirectional squeezed pile and squeezed branch grouting pile, the possibility and reliability of pile completion was tested, which could provide the effective proof for the pile type selection and the construction of engineering pile.
