Combined with specific engineering example,the reasons of adopting cutting wing box beam were analyzed and the performing method of cutting wing box beam was introduced,the construction technology of cast-in-place flange plate was illustrated detail.

The experimental and calculated results both showed that the distortion effect on the widely-flanged box girder section is particularly notable.

The construction technology of simply supported-continuous small box girder of Wanjiahu large Bridge;

On the construction method of small box girder erection in small area

With a three-span simple-supported then continuous small box girder bridge for the object to study and in consideration of the vertical and transverse variation of the temperature field, ANSYS is adopted to build a spatial model for analysis and calculation of the combined stress of short action effects, with emphasis on the influence of temperature stress on control of the combined stress.

Analysis of Transverse Load Distribution of Multi-box Girder Bridge and Its Experimental Study;

Based on the virtual laminated element program,the ultimate loading capacity of a typical 5-span prestressed concrete simply supported continuous multi-box girder bridge is calculated and analyzed by both the geometrical nonlinearity and material nonlinearity effect.
