摘要
阐述了高速公路中小跨径桥梁适应性评定的基本要求,以京港澳高速公路槐河大桥为工程实例,对桥梁承载能力、通行能力及抗洪能力进行了具体量化,在此基础上进一步提出了桥梁"安全使用度"的概念,为桥梁适应性评定结果量化提供了一种新的思路。
This paper expounds the basic requirements of the adaptability evaluation of small or medium span highway bridge, taking the Huai River Bridge on Beijing, Hong Kong and MacowExpressway Extension as a projeet example, on the bridge loading-bearing capacity, capacity and capability of flood control for specific quantification, and further proposed the bridge ＂Security Measure ＂, provides a new idea for the results of quantitative evaluation oforidge adaptability.
