一、前言 横向悬臂砌拱法(悬砌法),在我国房屋建筑拱式结构的屋盖上首先运用。建成的最大拱跨为10米。1961年,公路桥梁的建造也开始运用这一经验,交通部交通科学研究院与广东省交通厅科学研究所协作,修建了一座2—5米阶形块圆弧拱;内蒙也用碳化材料制成的阶形砌块建成一座净跨2米的拱涵,实践均获成功。在此基础上,又从改变拱块形状来研究如何适应大跨径拱的要求,接着在最近两年间我们又同
First, the foreword Horizontal cantilever arch method (hanging method), the first in the roof of the arch of our country building architecture. Built into the largest span of 10 meters. In 1961, the construction of highway bridges began to use this experience. In collaboration with the Institute of Communications of the Ministry of Communications of Guangdong Province and the Institute of Communications of the Ministry of Communications, a 2-5-meter stepped arched arch was also constructed. Inner Mongolia also used carbonized materials Into a stepped block into a net span of 2 meters arch culvert, the practice has been successful. On this basis, we also studied how to adapt to the requirements of the long-span arch by changing the shape of the arch. Then in the last two years we again
