基于预应力技术的路桥施工探讨

he construction of road and bridge based on the prestressed technology

为促进我国高速公路技术的发展和完善路桥施工建设的进程,预应力技术在其中发挥了举足轻重的作用,在现代路桥建设中被广泛采用。它所具备的高强度和高刚度以及抗渗透性和抗开裂性的混凝土技术具有不可替代的优越性。本文主要阐述了预应力技术在桥路施工中的技术问题和相关特性。

In order to promote the development of the technology in China and the process to improve the construction of road and bridge,prestressed technology plays a decisive role,is widely used in modern building. It has high strength and stiffness and anti permeability of concrete technology and anti cracking has irreplaceable superiority. This paper mainly describes the technology and related properties of prestressed technique in road and bridge construction.
