Compared with the results for some cross sections of a real example by means of calculation programme of finite element,it shows some distributing rules of stress in cross sections of concrete box girders of high-speed railway and some influencing factors.

Combined with engineering situation and geological prospecting data of 900 t high speed railway box beam,the entablement foundation design principle and some design parameters were discussed,the foundation treating calculation and results of entablement were profoundly discussed,therefore guaranteed the practicability and economy of foundation treating method.

Observation and research on temperature distribution in concrete box girders;

Research on concrete box girders temperature stress;

Aimed at the unreasonable calculation methods for cantilever slabs of concrete box girders,based on FEM and some kinds of calculation methods,a analyses is performed by sub-model technique to study the influence of several parameters,such as distortion for box girders,length and degree of slope for cantilever slabs as well as load location.
