摘要
混凝土安全性能的优异和降低造价成本等优点使得预应力混凝土在我国20世纪50年代以后得到了显著发展,鉴于预应力混凝土在桥梁中的广泛使用,为了解其内部抗震影响因素,查阅在桥梁上因抗震问题导致桥梁倒塌的相关工程案例,总结其发生特点,深入研究影响预应力混凝土抗震的因素,并对结果进行梳理。
Due to the excellent safety performance of concrete and the advantages of reducing the cost,prestressed concrete has been significantly developed in China since the 1950s.However,with the collapse of some bridges,we began to study it.In view of the extensive use of prestressed concrete in bridges,in order to understand its internal anti-seismic factors,the relevant engineering cases of bridge collapse caused by anti-seismic problems on bridges were consulted,their occurrence characteristics were summarized,the factors affecting the anti-seismic of prestressed concrete were deeply studied,and the results were combed.
