In recent years, with the advanced requirements for speedup and heavy load from rail transport, the advanced requirements for the property of supporting pedestal have been proposed. The inherent defectivenesses which include the low mechanical property, low fatigue ductility and low shock resistance of cast-steel product, and the avoidless gas cavity, shrinkage porosity, inclusion, crack, etc in cast-steel product, existed in the product of Cast-steel supporting pedestal, have threatened the high speed and safe running of railroad.

近年来，随着铁路运输对重载、高速要求的提高，对关键部件支撑座的性能要求也在提高，铸钢支撑座产品存在的固有缺陷(铸钢件本身的机械性能、疲劳韧性、抗冲击性能都不高，铸件产品无法避免地存在气孔、缩松、夹杂、裂纹等)对铁路高速安全运行已构成威胁。

In this paper,a new steel-concrete composite spine girder with large cantilevered beams of corrugated steel web is introduced.

The microstructure of G99 is sub structure with refined lath martensite and high dislocation density ,uniform and carbonide particles strengthing matrix distribute on it,establishes good foundation for getting high strength and toughness for this stell.

G99钢的显微组织是具有细化的板条马氏体、高位错密度的亚结构组织、在该组织上分布均匀、细小的炭化物颗粒强化基体，为钢的高强高韧奠定了良好基础。

The results show that upper bainite of 9Cr2Mo Steel and GCr15 steel is feathery and the upper bainite carbide is lamellar or claviform. The upper bainite carbide distributes between the subunits of bainite ferrites by and large parallelly to the axis of bainite ferrites. Lower bainite of 9Cr2Mo Steel and GCr15 steel is in bamboo leaf shape and the lower bainite carbide is in shred or fibre shape. The lower bainite carbide distributes between the bainite ferrites, furthermore, the angles between lower bainite carbonide and the principal axis of the lower bainite ferrites are unequal.

结果表明，9Cr2Mo钢和GCr15钢的上贝氏体组织呈羽毛状，上贝氏体碳化物呈长短不一的薄片状或短棒状，分布在铁素体亚片条或亚单元之间，其排列与贝氏体铁素体片条轴向大体上平行分布；下贝氏体组织呈竹叶状或针状，下贝氏体碳化物呈细片状或纤维状等形状，分布在铁素体片中间，大多数与片条的主轴方向交角排列，但角度不等。
