近年来,在各国桥梁建筑实践中,悬臂施工的预应力混凝土桥得到了普遍的推广。我国公路自1960年起,曾作过悬臂浇筑大跨径桥的设计和悬臂拼装的设计方案。但由于这种桥梁的设计我国还是第一次,须先做一座实验桥以便推广。交通部把这个实验桥修建任务交给了江苏省交通厅,并组织上海公路科学研究所等有关单位参加协作。在党的正确领导关怀下和职工群众的积极努力下,这座干接头上部构造悬臂拼装预应力混凝土T形
In recent years, in the practice of bridge construction in various countries, prestressed concrete bridges with cantilever construction have been widely popularized. Since 1960, the highway of our country has been the design of cantilever pouring long span bridge design and cantilever assembly. However, due to the design of such a bridge for the first time in our country, we must first do a pilot bridge in order to promote it. The Ministry of Transportation handed over the task of constructing the experimental bridge to the Communications Department of Jiangsu Province and organized the Shanghai Highway Science Institute and other relevant units to participate in the collaboration. Under the correct leadership of the Party and the active efforts of the workers and the masses, the upper part of this dry joint is constructed with cantilever assembled prestressed concrete T
