| Summary: | The internal force generated by the arch structure under the external load is almostconverted to the uniformaxial pressure.According to the arch structure characteristics,the frontand rear stress face-slabs of the box girder structure and other traditional wing walls areimproved to double-side multi-arch. And through the arch effect, the bending moment and the shearforce arising from the horizontal water pressure,horizontal earth pressure and other effects born bythe front water-facing surface and rear soil-retaining surface can be almost converted into theaxial force of the arch structure, which makes full use of the compressive strength of the archconcrete, so without reinforced bars or with less construction albars in this arch, the archthickness is thinner, and the concrete materials and engineering investment are saved. At the sametime, the arched face slabl structure can be prefabricated into tiles in the factory, which arethen transported to the construction site and assembled into the whole, so it cansimplify theconstruction process to facilitate the construction, improve the construction quality,shorten theconstruction period, and save total investment. Based on the specification design, and the researchachievements of the wings wall structure of a sluice, this paper lays a foundation for the furtherresearch, and provides the corresponding reference standard. |
