摘　　要：随着路桥施工技术的发展,预应力技术被广泛应用到现代高速公路路桥施工中。预应力技术利用拉力和应力相互抵消,在高速公路路桥施工中起到至关重要的作用,可有效避免外部压力导致的裂缝问题,使路桥结构更加稳固安全。以预应力技术为研究对象,对预应力施工技术的概念与特点进行阐述,探究了预应力技术在我国公路桥梁施工中的具体应用,旨在提升公路桥梁整体施工水平,从而促进社会经济健康快速发展。With the development of road and bridge construction technology,prestressed technique has been widely used in modern highway road and bridge construction.Prestressed technique utilizes tension and stress to offset each other,which plays a vital role in highway road and bridge construction.It can effectively avoid cracks caused by external pressure and make the bridge structure more stable and safe.This paper takes prestressed technique as the research object,expounds the concept and characteristics of prestressed construction technique,and probes into the concrete application of prestressed technique in highway road and bridge construction in China,aiming at improving the overall construction level of highway road and bridge and promoting the healthy and rapid development of social economy.
