赵州桥原名安济桥,俗称大石桥,建于隋炀帝大业年间(605—616年),至今已有1300年的历史,是现存的世界上最古老的石拱桥。石拱桥是用石块拼砌成弯曲的拱作为桥身,上面修成平坦的桥面,以行车走人。赵州桥的特点是“敞肩式”,即在大拱的两肩上再辟小拱,是石拱桥结构中最先进的一种。在欧洲,这种结构迟至十四世纪才出现,就是法国的赛雷桥,比赵州桥晚700多年,并且早已毁坏。一、制作材料:1.泡沫塑料平板(包装类废品);
Zhaozhou Bridge was formerly known as Anji Bridge, commonly known as Dashiqiao. It was built in the year of the Sui Dynasty (605-616) and has a history of 1,300 years. It is the oldest stone arch bridge in the world. The stone arch bridge is made up of curved arches that are made of stones to form a bridge, and a flat bridge is built on it to drive away. Zhaozhou Bridge is characterized by “open shoulder style”, that is to say, a small arch is built on the shoulders of the big arch. It is the most advanced type of stone arch bridge structure. In Europe, this structure did not appear until the fourteenth century. It was the French Sai Lei Bridge, which was more than 700 years late than the Zhaozhou Bridge, and it was already destroyed.
