The hand boring piles are commonly used foundations of high-rise buildings, especially in some underdeveloped districts or cities of China. The testing of hand boring piles is more difficult because the diameters are larger and the load-carrying capacities are higher. From the angle of practical application,this paper analyzes and sums up the testing method of integrity and load-carrying capacity. In addition, the paper puts forward the way of judging the deficiency and the pile and the elementary judging basis of enlarging the size of the holes and illustrates the effect of the testing method with cases.
