在工程结构设计的过程中,保证结构设计的安全耐久行以及适用性是其基本的要求,一般的钢筋混凝土虽然可以在一定程度上保证工程结构的安全性,但是由于其一定的特殊性,使得钢筋混凝土的耐久性以及适应性还存在很大的弊端。而预应力混凝土的应用可以在工程实践中很大程度上保证工程的抗渗性以及抗裂能,所以说预应力混凝土有着很大的优势,在工程中进一步加强对其应用发展有着重要的现实意义。基于此,本文将着重分析探讨桥梁施工中预应力技术的应用,以期能为以后的实际工作起到一定的借鉴作用。 In the course of engineering structural design, it is the basic requirement to ensure the safety and durability of structural design and its applicability. Although general reinforced concrete can ensure the safety of engineering structure to a certain extent, due to its particularity, The durability and adaptability of reinforced concrete still have great drawbacks. The application of prestressed concrete in engineering practice to a large extent, to ensure impermeability and crack resistance, so that prestressed concrete has a great advantage in the project to further strengthen its application and development has an important reality significance. Based on this, this article will focus on analyzing and discussing the application of prestressing technology in bridge construction, with a view to be able to play a certain role in reference for future practical work.
