ANALYSIS OF VERTICAL BEARING CAPACITY OF SINGLE PILE TO ROTARY CAST-IN-SITU PILE IN A PROJECT OF SOUTHEAST ASIA

Pile static load test is a common method to determine ultimate bearing capacity of single pile, the research about domestic project is abundant at present, however the cases from overseas projects are scanty, and most of the studies did not reach limit stat of pile foundation, test data were incomplete, so it is necessary to carry out destructive tests of pile foundation. Therefore, the study, combining with a project of Southeast Asia, finished destructive test of single pile ultimate bearing capacity of vertical compressive by static load test to 6 test piles of subsidiary factory in this project, analyzed the process of the vertical ultimate bearing capacity of single pile test by Q~t curve and S~t curve, determined single pile vertical ultimate bearing capacity according to the specifications, accumulated experiences for similar project in the region, contributed the precious experiment data for further research.
