摘要
拱结构的受力有一定的特殊性 ,而拱的拆除施工更容易发生事故。原上海市延安西路高架收费口的主体结构是现浇钢筋混凝土拱结构 ,拱脚以预应力索拉接。配合沪青平高速公路入城段工程的建设需要 ,该拱于 2 0 0 0年 10月被拆除。结合该施工实例 。
As the force on the arch is very complicated, its removal is apt to accidents. The arch at the toll gate on Yan'an Rd(W) is an in situ reinforced concrete structure, with tendons stretching the feet thereof. As required in construction of Hu Qing Ping Freeway Project (the Entrance Secition), the arch was removed in Oct. 2000. Taking that for example, discussions are held here on the technique for removal of similar RC arches.
