1·At the same time, the high web structure was researched, and the deformation and stability of the vertical and level stiffener was analyzed.

同时，对高腹板结构设计进行了研究，对竖向与水平加劲肋的刚度及稳定性进行了计算分析。

2·The major parameters including the curvature radius, the ratio of height to span, the ratio of height to width, the thickness of web, the stiffener density and the diaphragm density are studied.

主要研究了曲率半径、宽跨比、高宽比、腹板厚度、加劲肋数量、横隔板间距等结构参数对曲线钢箱梁承载力和变形特性的影响。

3·Settling for strength and stabilization of web, it avoids putting web's carrying capacity down owing to constructing technics by increasing thickness of web and lessening the stiffener;

在满足腹板强度和稳定要求的同时，为避免施工工艺对钢箱梁腹板承载能力的削弱可采用加厚腹板，少加加劲肋的方法来改善；
