1.前言近几年来,由于世界经济危机,各发达国家的建设工程量减少,国际竞争激烈,故在建设工程技术方面有较大的发展。新技术发展的方向,是以缩短现场劳动时间、作业单一化、提高结构物质量等为研究开发的目的。以是否提高结构物质量来判断其开发、发展的意义。本文将简要介绍近几年来,国际上预应力混凝土桥梁设计、施工方面的发展,特别是与日本的现状不相同之处,以便从中得到启发。
1. Foreword In recent years, due to the global economic crisis, the number of construction projects in various developed countries has dropped and the international competition has been fierce. Therefore, there has been a great development in the construction and engineering technologies. The direction of the development of new technologies is to shorten the on-site labor time, work-oriented, improve the quality of the structure for the purpose of research and development. Whether or not to improve the quality of the structure to determine the significance of its development and development. This article will briefly introduce the international design and construction of prestressed concrete bridges in recent years, especially with Japan’s current situation is not the same place, in order to be inspired.
