摘要
斜拉索作为斜拉桥的主要受力构件,随着大量斜拉桥的投入使用,斜拉索的病害问题也日益凸显,如何在日常养护中加强对斜拉索的检查维护,延长其使用寿命,保证桥梁承载及通行能力,意义重大。根据南二环高速公路甘竹溪、李家沙特大桥2017年斜拉索检查维护情况,就斜拉索的结构组成,介绍了病害及检查维护方法。
As cables being the main force components of cable-stayed bridge,with a large number of cable-stayed bridges being adopted,the disease problems of cable have been also growing,it has been of great significance that how to strengthen in the daily maintenance of stayed-cables inspection maintenance,prolong the service life and guarantee the bridge load and capacity. In this paper,being based on the inspection and maintenance for the cables in 2017 at Ganzhuxi and Lijiasha Bridge in South Second Ring Expressway,several experiences have been discussed regarding the structural composition of the stayed cables,common diseases and inspection maintenance methods.
