| Abstract: | With the Songhua River bridge as a practical example,the basic principles of the self-balancing measuring and testing techniques are introduced in the paper,with the design and construction of the test pile briefly dealt with.By analyzing the measured results of the test pile,the pile-end resistance,pile-side resistance and the ultimate bearing capacity are acquired.The result of the test proves that the method has quite good accuracy.All the related data form a reliable basis for design units in optimizing the design of pile foundations,as well as serve as a useful reference for similar projects in the future. |

| Keywords: | self-balancing technique the load-bearing capacity of a single pile resistance at the pile-end pile-side resistance displacement design of pile foundation |
