Contrast analysis about the result of static load test and high strain testing for the bearing capacity of screw pile foundation

摘要

Firstly, the technology of screw pile is introduced briefly. It has high body quality, high bearing capacity and wide application prospect. Then, based on engineering examples, the results of static load test and high strain testing for the bearing capacity of SCREW PILE foundation are analyzed contrastively. The bearing capacity value tested by high strain dynamic testing is higher than the static loading test's with 13%～21%, which should be attached importance in the check and accept and application of the screwed pile. The analysis and sum up of testing results should be considered to the design and application of screwed pile, providing some reference to the quality judge and bearing capacity confirming is another purpose in the paper.
