SFRC降低桥梁高度的作用分析与实例

采用一个公路桥梁设计实例 ,讲述在一些特殊条件下 ,采用SFRC制作桥梁 ,可以使桥梁高度得到降低 ,同时也能更好满足设计要求。论述过程中采用目前的一些桥梁理论和公式 ,涉及钢纤维混凝土部分 ,采用成熟的计算公式 ,不成熟的想法只作概念探讨 ,对于复杂的T型梁截面极限承载力计算也进行了探讨

Analysis of action in reducing the height of bridge by SFRC

Based on the design example of bridge, the probability of reducing the height of the bridge and meeting primely the design requirements by SFRC bridge in some special condition is discussed in his paper. Some actual theories and formulas of bridge are adopted in this paper, and mature calculation formulas are used when dealing with steel fiber concrete, and immature ideas are discussed only in conception, as well as the ultimate capacity calculation of complex T beam section.
