随着我国建筑行业的发展,对路桥工程的要求越来越高,预应力技术就应运而生。预应力混凝土相比普通混凝土,具有更好的抗渗和抗裂作用,预应力技术在路桥工程中得到了广泛的应用。本文就预应力的特点及路桥施工中预应力技术的应用做了简要说明,为路桥施工中采取预应力技术的结构提供参考。
With the development of China’s construction industry, the requirements of road and bridge engineering are getting higher and higher, prestressed technology came into being. Compared with normal concrete, prestressed concrete has better impermeability and anti-cracking effect. Prestressed technology has been widely used in road and bridge engineering. This paper gives a brief description of the characteristics of prestressing and the application of prestressing technology in the construction of road and bridge, providing references for the structure of prestressing technology in road and bridge construction.
