联合加固的钢筋混凝土简支板桥研究

讨论钢筋混凝土简支板桥的病害及成因，介绍联合应用改造多跨简支梁为桥面连续简支梁体系、增大构件截面、粘贴钢板加固等加固技术进行加固的过程，借助ANSYS建立有限元模型进行仿真分析，并通过实桥检测来验证改造多跨简支梁为桥面连续简支梁体系和粘贴钢板加固法的可靠性、可行性及加固效果，对中小跨径简支体系桥的加固和承载力提高有一定借鉴作用。

Research on Simply Supported Slab Bridge of Reinforcement Concrete by Joint Consolidation

This paper discusses damages and causes of the simply supported slab bridges of reinforcement concrete, introduces the consolidation process by means of consolidating techniques of consolidated application of modified muhispan simply supported beams as the continuous simply supported beam system of bridge surface, enlargement of structure section and pasting steel plates, etc. The paper performs emulation analysis by establishing the finite element model with the help of ANSYS and verifies it via the detection for practical bridges the reliability, feasibility and consolidating effect of consolidating methods by modifying multispan simply supported beams as the continuous simply supported beam system and pasting steel plates, which is intended to be a reference for consolidation and bearing capacity of the mediumsmall-spans simply supported system bridges.
