The underground canteen of Beijing No.55 Middle School is adjacent to the basement structure of a classroom building at the north side, no space was remained for retaining pile because of the site restriction in the north of underground canteen foundation pit, and soil nailing wall support cannot meet the strict requirements of surroundings on the displacement and settlement of excavation. In this case, an embedded “pre-stressed anchor ribbed plate wall” was designed and adopted to replace the pile-anchor support structure. Combined with the engineering case of foundation pit support, this paper introduces the parameters design and construction measures for the pre-stressed anchor and ribbed plate wall structure.
