The foundation of a 2×300 MW pithead’s power plant in southwest of Shandong Province is located in alluvial layers of the Yellow River.In this paper,the authors test the pile body with low strain integrity testing methods, determine the vertical ultimate bearing capacity of single pile using two methods such as high strain tests and static load tests, and contrast the advantages/disadvantages and affecting factors. Then the authors conclude the following three results. 1) testing results by high strain CAPWAP method after fitting agree well with that by the vertical static load of a single pile; 2) when it is not allowed for in-situ static load test, high strain tests can be used as a supplement means to the load test for pile foundation; 3) when the authors get more reliable high strain test results, some adjustments can be made for the design scheme according to standard method based on rigorous calculation.
