人教部编版语文八年级上册中国石拱桥教案
中国的拱桥的历史可追溯到东汉时期，至今已有一千八百多年。中国的拱桥别具一格，造型优美，曲线圆润，形式多样，世界罕见。拱桥按照建筑材料分为石拱桥、砖拱桥和木拱桥，其中较为常见的是石拱桥。拱桥又分为单拱、双拱、多拱，拱的多少根据河面的宽度而定。多拱桥一般正中间的拱较大，两边的拱略小。根据拱的形状，又分五边、半圆、尖拱、坦拱。桥面上铺板，桥边有栏杆。单孔拱桥的拱形呈抛物线的形状，如北京颐和园的汉白玉石桥玉带桥。多孔拱桥适于跨度较大的宽广水面，常见的多为三、五、七孔，以奇数为多，偶数较少。当多孔拱桥某个孔的主拱受荷时，能通过桥墩的变形或拱上结构的作用把荷载由近及远地传递到其他孔主拱上去，这样的拱桥称为连续拱桥，简称“联拱”。如建于唐代元和年间的古桥苏州宝带桥，桥下共有53个孔相连，桥孔之多，结构之精巧，为中外建桥史上所罕见。
