在拱桥(尤其是圬工拱桥)的理论研究中,最引人注目的问题之一是对于主拱圈轴线的研究。由于合理拱轴研究涉及的问题较多,特别是动荷载影响及高次超静定拱结构的研究常遇到一些极为复杂的理论问题,因此,直到现在还不能说已经圆满地解决了这个问题。 拱桥在较长时期内仍将是我国主要的桥型之一,因此更有深入研究的必要。为了相互学习、共同提高,现将我们的认识和看法综述如后,不妥之处,请指正。
One of the most striking issues in the theoretical study of arch bridges, especially those of masonry arch bridges, is the study of the principal arch axis. Due to the many problems involved in the research of rational arch axis, especially the study of dynamic load influence and high-order statically indeterminate arch structure often encounter some extremely complicated theoretical problems, so it can not be said until now that this problem has been satisfactorily solved . For a long time, the arch bridge will still be one of the major bridge types in our country, so it is necessary to conduct further research. In order to learn from each other and improve together, it is now appropriate to summarize our understanding and opinions as follows.
