多孔双曲拱桥在宽河上经常可以遇到,而双曲拱桥墩日益向轻型化发展,由此导致墩的刚度减小,连拱作用显著。因此,考虑连拱的作用,将使计算比较符合实际,用材比较节约。而探讨一个既比较简便而又能够达到一定精度的连拱计算达法,就显得较为重要了。 在连拱计算方面,湖南的同志们作了许多工作,建立了一个简化计算的系统[见参考资料
Porous double-curved arch bridge can often be encountered in the wide river, and double-curved arch piers increasingly lightweight development, resulting in the pier stiffness decreases, even the role of significant arch. Therefore, considering the role of arches, the calculation will be more realistic and more economical. However, it is more important to explore a method of calculating double arches, which is both simpler and more accurate. In terms of arcades, comrades in Hunan have done a great deal of work to establish a system of simplified calculations [see Resources
