Abstract
Using continuous girder, Wuhan-Xianning Intercity Railway spans above Wuhan-Guangzhou High-speed Railway near the town of Henggouqiao in Xianning city, and then the concreting construction in situ above Wuhan - Guangzhou High-speed Railway may bring great safety risk to the operation of Wuhan-Guangzhou High-speed Railway. Therefore, during the construction of the continuous girder, according to different working procedures characteristics, several technical safety measures were employed such as covering, isolating, consolidating, staring the site by security personnel, utilizing construction interval to avoid high-risk points. As a result, these technical safety measures effectively ensured the operation safety of Wuhan-Guang High-speed Railway, and it also has a good reference value for similar project's safe protection.关键词
