Cause Analysis and Treatment of Common Quality Defects of High-speed Railway Box Girders
High-speed railway,as an important part of Chinese transportation infrastructure,its construction lev-el and construction technology have reached the world-class level,and it has also become a business card of Chi-nese infrastructure construction to the world.Prefabricated box girder construction is widely used because of its high economy and good stability.However,due to the structure of prefabricated box girders,many quality defects often occur during the construction process,which have not been completely resolved until now.This paper summarizes and analyzes the causes,prevention measures and treatment methods of common quality de-fects of high-speed railway box girders based on the construction experience of prefabricated box girders.
