一、引言斜张桥是一种古老的体系,起源于16世纪的欧亚各文明古国。十九世纪初为满足当时交通的迅速发展而建造的斜张桥却由于材料品质差和对其非线性力学性质缺乏了解而屡遭失败,使这一古老体系被悬索桥所替代而隐没了将近一个世纪。1938年,德国工程师 Dischinger 重新发现了斜张桥,并在现代高强度钢材和力学 I. INTRODUCTION The Oblique Bridge is an ancient system that originated in the 16th-century ancient civilizations of Europe and Asia. The oblique bridge built to meet the rapid development of traffic at the beginning of the 19th century was repeatedly defeated due to poor material quality and lack of understanding of its nonlinear mechanical properties. This ancient system was replaced by a suspension bridge and it was almost a recession. century. In 1938, the German engineer Dischinger rediscovered the diagonal bridge, and in modern high-strength steel and mechanics
