The present application relates to the field of slope support
engineering, and provides a
retaining wall with a combination of a retaining plate and an unloading plate and a method for calculating internal force of the
retaining wall, which comprises a bottom plate, a first vertical plate, a second vertical plate, a retaining plate and an unloading plate, all of which are
reinforced concrete structures; the
retaining wall structure is filled with backfill behind the structure; the first vertical plate is arranged on the bottom plate, the second vertical plate is arranged directly above the first vertical plate, and the first vertical plate, the second vertical plate and the retaining plate are overlapped; the unloading plate is arranged between the first vertical plate and the second vertical plate, and forms an unloading and decompression platform; the unloading plate is overlapped with the adjacent retaining plate, the first vertical plate and / or the second vertical plate. The combination of the retaining plate and the unloading plate effectively reduces the horizontal earth pressure acting on the retaining wall, reduces the internal force of the structure on the retaining wall, including
shear force and
bending moment, reduces the horizontal displacement of the retaining wall, and reduces the cross-sectional size of the retaining wall structure, thereby reducing the difficulty and cost of
engineering construction.
