摘要
以某混凝土连续梁桥出现梁端裂缝为工程背景,描述了裂缝状态,对其进行理论分析和数值模拟,分析了裂缝成因,提出了预应力补强措施和施工方案,对该类型的桥梁维修有着积极的参考意义。
Based on the engineering background of the cracks at the beam end of a concrete-continuous continuous beam bridge, the crack state was described, the theoretical analysis and numerical simulation were carried out, the causes of the cracks were discussed, and prestressed reinforcement measures and construction schemes were proposed. Maintenance has a positive reference significance.
