Comparison of load test results between self-balanced method and static pressure method

The applications of self-balanced method and the pile load test using tension-press-anchor system under large tonnage load in static loading tests are introduced.Both the methods are used in bearing capacity tests on pile foundation of Yellow Taohuayu River Bridge.The results are compared and show that the error is very small.Using the self-balanced method,pile body is divided into two segments.The load is applied by the pile body.The proposed method is more convenient and inexpensive,and it can be popularized in engineering.
