The invention discloses a field test method for testing the neutral point of negative friction resistance of PHC pipe piles in soft soil areas. The steps are as follows: 1) stratum layering: using a drilling rig to drill holes in the manner of spiral drilling to obtain the stratum of the soil around the pile Layer information; 2) Embedding of layered settlement equipment: lay the inclined pipe flat on the ground, and insert it into the settlement ring sequentially from the bottom. The stratum information obtained from the number and position of the settlement ring is determined, and the settlement plate is fixed on the pile head ;4) Surcharge: carry out surcharge to the area surrounded by the pile head and the inclined pipe, the surcharge soil is cohesive soil, and roll it with a roller compactor while surfacing until the surcharge reaches a height; 5) Settlement data collection : Connect the layered settlement probe and the layered settlement data acquisition instrument respectively with the two ends of the measuring line, vertically lower the layered settlement probe into the inclined pipe, and repeatedly test the layered settlement data; 6) calculation and analysis. The method is easy to operate and easy to operate, and can effectively solve the problem of distortion of the neutral point of negative friction resistance of PHC pipe piles obtained by laboratory tests at present.
