马鞍型(又称双曲抛物面型)无筋薄壳渡槽是兼有拱式、梁式渡槽优点的新型渠系建筑结构。它把无筋拱式渡槽的槽身、排架和主拱三种构件合为一体,既是过水又是传递和支承荷载的构件,而且主要承受压应力,因此构件少,材料特性可以充分利用,从而可以收到显著的技术经济效果。 Saddle type (also known as hyperbolic parabolic) non-reinforced shell aqueduct is both arch and beam aqueduct advantages of the new canal structure. It combines the body, arch and main arch of the non-arched aqueduct into one body, which is not only the component that transmits water and supports the load, but also mainly bear the compressive stress, so there are few components and the material characteristics can be fully utilized , Which can receive significant technical and economic results.
