老旧桥梁维修加固是当前桥梁养护工作的重中之重。预应力高强钢丝绳技术作为一种新兴的主动加固措施,在中小桥加固领域独具优势。笔者以实际工程为例,简要介绍该技术,并利用理论分析和有限元模拟方法研究其应用效果,为其广泛推广提供参考。
Old bridge repair and maintenance is the most important bridge maintenance work. Prestressed high-strength wire rope technology as a new active reinforcement measures, in the field of small and medium-sized bridge reinforcement unique advantages. The author takes the actual project as an example, briefly introduces the technology, and uses the theoretical analysis and the finite element simulation method to study its application effect, providing reference for its widespread promotion.
