摘要
通过对合蚌高铁(76+160+76)m连续梁拱组合结构的研究,介绍了主桥结构设计要点和施工方法,指出采用"异位拼装,纵向就位"的主拱架设方法,解决了传统方法中拼装时间长,给桥下既有铁路带来安全隐患的难题,降低了运营风险。
According to the research on （76 ＋ 160 ＋ 76）m continuous beam arch combination structural design along Hefei-Bengbu Express Railway, the paper introduces the design points and the construction methods of the main bridge structure, points out the main arch erection method of the non-bridge-place assembling and longitudinal positioning, and solves the safety hidden hazards on existing railway caused by the long assembling period of the traditional methods, so as to relieve the operation risk.
