高速公路桥梁养护加固中新型预应力技术的应用方法

Application Method of New Prestressed Technology in Maintenance and Reinforcement for Expressway Bridges

随着高速公路的频繁使用和年限的不断增长,公路桥梁容易出现各种质量问题,从而对公路桥梁的牢固性造成不良影响,严重影响桥梁的正常使用,因此需要进行维修和加固。新型预应力技术是一种比较先进的施工技术,它不仅能改善桥梁的加固性能,还能保证结构的稳定性,增强桥梁的强度,从而延长其使用寿命。阐述了预应力技术在高速公路桥梁养护和加固中的应用方法。

With the frequent use of expressways and the continuous increase in age,it is easy to occur various quality problems of expressway bridges,causing adverse influences on the firmness of the bridge which seriously affected its normal use.Therefore,they need to be repaired and reinforced.The new prestressed technology is an advanced technology that not only improves the reinforcement effect of the bridge but also ensures the structural stability to strengthen the bridge and thus prolong the service life.This paper expounded on the application method of the prestressed technology in the maintenance and reinforcement of expressway bridges.
