Theoretical simulation and factors for static loading tests on a single pile

A method for simulating the static loading test on a single pile is established based on the Mindlin’s settlement solution, including surcharge loading tests and anchor pile loading tests. The two kinds of test load are compared, and the factors for the test results are analyzed. The influences of arrangement of a bridge with temporary supports or anchor piles on the static loading tests on a single pile are emphasized. The results show that the surcharge and archor pile loading tests exaggerate the pile rigidity, and the exaggeration of the former is less than that of the latter. Additionally the static loading tests according to the Chinese code in some conditions will cause more errors. Therefore the interaction of the uprising of datum piles due to unloading of the bridge with temporary supports or pulling of anchor-pile and lowering of datum piles due to loading of test piles may be fully used to decrease the influences on the results.
