摘要
Abstract
The control value of transverse horizontal displacement of bridge pier's top should be inversely calculated based on horizontal angle limited-value of beam end specified in the design code, so as to guide the bridge substructure design of high-speed railway. The back calculation method which is commonly used nowadays was researched in this paper. The research results showed that common algorithm was completely applicable to simply supported beams with common spans (I. E. 20 m, 24 m, 32 m) , whereas in the case of continuous beam bridges and other types of bridges with similar spans, the applicability was limited. A modified back calculation method was addressed in this paper, and the result showed that the modified method was right and reasonable.关键词
