摘要
结合工程实例,通过对国内首座六跨中承式飘带形提篮拱桥进行静、动态有限元数值模拟,分析结构的受力特点,制定合理的静、动态试验研究方案,进行实桥荷载试验,研究桥梁实际受力状态与设计状态的相符性,为该类桥梁的检测与评估提供理论依据。
During the section from Changchun to Siping in the reconstruction and extension project of Beijing - Harbin Expressway, to effectively control the differential settlement between new bridge and old bridge, the post grouting technique behind pile tip shall be used in cast - in - situ bored pile foundation of widening bridge. The construction technological controlling measures of pile tip post grouting, construction controlling essentials and technological process are explained and the characteristics of pile tip post grouting technique are summarized.
