摘要
22跨拱桥式渡槽爆破拆除时要求保留拱墩,以备重修渡槽时使用。介绍了渡槽拆除的方案、预处理设计、爆破参数以及控制飞石和防止曲拱梁及槽身塌落对拱墩造成损伤等采取的措施。
When the two-arch bridge aqueduct is demolished by means of explosive method,it＇s piers must be preserved for construction of a new aqueduct. In this paper, the design program, pretreatment, parameters selection and safety protection measures are introduced. The falling down procedure which can destroy the piers of arch beams and aqueduct are analyzed, and the measures which can be used to protect the piers are discussed.
