Distributive regularities of inner force of pile under static and dynamic load, the change of pile's side resistance, and settlement of piles are analyzed by static and dynamic load test.

In this article, the bearing capacity behavior and load transfer mechanism of super long bored pile in Wenzhou soft clay are discussed, on the basis of the static loading test and axial force test.

Impurity pump mechanical seal after static test, the operation of high-speed rotation of the centrifugal force generated will inhibit the leakage of media.
