| Abstract: | The self-balance test method is adopted for Hangzhou Bay Bridge to test the capacity of the bored pile .Two load-boxes are buried in the pile to test the effect of improving the capacity of the pile by injecting cement into the bottom of the pile. The practice has proved that this test method has great advantage to test large capacity pile in the sea and it will find wide application prospect in bridge piles. |
