本文是万江大桥撑架式预应力混凝土箱型连续梁设计与顶推法施工总结摘要的部分内容。——编者交通部曾在1975年下达给我们一项研究大跨径预应力混凝土桥梁结构和施工方法的任务。我们认为:大跨径桥梁结构设计的进展是与施工技术上的革新密切相关的,而上部构造如何进行架设更是一个关键问题。为了考虑施工方法,我们曾参考了国外资料,西欧在六十年代首创了顶推施工技术。以后通过委内瑞拉的卡罗尼桥的实践,作出范例,为预应力混凝土连续梁桥上部构
This article is Wanjiang Bridge pillared prestressed concrete box continuous beam design and construction of thrust summary of the summary. - Editor’s Note The Ministry of Communications gave us a mandate in 1975 to study the structure and construction of large span prestressed concrete bridges. In our opinion, the progress of structural design of long-span bridges is closely related to the renovation of construction technology. How to set up the superstructure is also a key issue. In order to consider the construction method, we have made reference to foreign materials, and Western Europe pioneered the construction technology in the sixties. Later through the practice of Caroni Bridge in Venezuela, to make an example for the prestressed concrete continuous beam bridge superstructure
