Abstract： The static load test on piles is a method established theoretically undisputed pile test technology. In determining the ultimate bearing capacity, it is the most accurate, reliable method to determine whether some kind of dynamic load test method is mature or not, that is , the magnitude of error of the static load test results is the basis. Based on a case of a 110 kV substation project, for eight large-diameter rock grouting bored piles, the static load tests on vertical bearing capacity and uplift capacity of single pile are carried out. The test results are analyzed, and some useful conclusions are drawn.
