【Abstract】 This paper suggests two analytical methods of internal forces of arch aqueduct from the view point of the characteristics of its structural behaviour. Both methods confirm the interaction between main arches and rigidsuperstructures——2channels,spandrelpiers or columns and transverse brace-s, i.e.their deformations must be harmonic. The principle of this paper is compatible with each kind of arch aqueducts, such as double-curved arch aqueduct, ribbed arch aqueduct, trussed arch aqueduct etc.更多还原
