| Abstract: | The routine concrete arch culvert, which needs much concrete, is composed of the arch ring, the arch protection, the side-wall and the base. This article adopts new structure to take off arch protection and the side-wall. The arch culvert is composed of two parts of the arch ring and the inte- gral plate base. The optimum design uses the genetic algorithm to obtain the rational arch axis. The bending moment on the cross section is small. The culvert structure is simple. And the construction is convenient. |
