Study on new test technology of pile foundation bearing capacity

Abstract

A revolutionizing pile foundation testing technology, STATNAMIC has been analysis in the paper. This method is the testing method of bearing capacity for the pile foundation that has the advantages such as economical, speedy, accurate and reliable etc. By burning solid fuel in a combustion chamber, a controlled and pre-determined load is applied directly to the pile foundation without introducing high tension forces. The duration of loading is substantially longer than both the impulse produced by dynamic testing and the natural frequency of pile foundation. Moreover, owing to test without anchor pile, thus it would be able to save cost of manufacturing the anchor pile and the constructing period. And, finally it is not limited to the type of pile, the pile gradient and the surroundings of pile.
