我国经济总体水平不高,公路桥梁发展首先要着重于量大、面广的一般大、中桥。这类桥梁以预应力混凝土结构为主,要编制经济适用的标准图,提升施工水平和质量。其次是跨越大江(河)、海湾的特大型桥梁建设。随着我国经济高速发展,材料、机械、设备工业都相应发展,这为修建大跨径斜拉桥和悬索桥提供了有力保障,再加上科技的进步使设计水平和技术大幅提高,使我国建桥水平已跃身于世界先进行列。
The overall economic level of our country is not high. The development of highways and bridges must first of all focus on the large and medium-sized large and medium-sized bridges. Such bridges to prestressed concrete structure-based, to prepare an economic standard map, improve the level of construction and quality. Followed by the construction of large bridges across the river (river), the bay. With the rapid economic development in our country, the materials, machinery and equipment industries have been developed accordingly. This has provided a powerful guarantee for the construction of large-span cable-stayed bridges and suspension bridges. In addition, with the advancement of science and technology, the design level and technology have been greatly increased, Bridge level has been leapt to the advanced ranks of the world.
