三、平面曲梁的技术经济效果分析曲梁是近十多年来发展起来的一项新型桥梁结构,虽然国外已修建了不少曲线型桥梁,但国内尚缺乏这方面的实践经验和基础资料,故仅能就结构形式和体系方面作简要的分析,以说明曲梁的适用范围及其推广价值。考虑到曲梁的特殊性,以采用整体箱型结构为宜,故以此作为分析的基本形式。
Third, the technical analysis of the technical performance of curved curved beam Curved beam is a new type of bridge structure developed over the past decade, although a lot of curved bridges have been built abroad, but the domestic lack of practical experience and basic data , So only a brief analysis on the structure and system can be made to illustrate the applicable scope of the curved beam and its promotion value. Taking into account the particularity of curved beams to adopt the overall box-type structure is appropriate, so as the basic form of analysis.
