| Abstract: | The massive concrete of the gravity anchorage of Aizhai Suspension Bridge was cast by pumping.The batching plant for production of the concrete was arranged at a place 60 m high and horizontally about 150 m apart from the anchorage foundation pit.This paper mainly presents the successful experiences of resolving the technical problem of downward pumping of the concrete under condition of great fall head. |
| Keywords: | suspension bridge gravity anchorage massive concrete great fall head downward pumping technique |
