Abstract

Tokyo Metro Co., Ltd. constructed the No.13 subway line 8.9km long between Ikebukuro and Shibuya, and it was open for traffic in this June. This line's deepest point is between Zoshigaya station and Nishi-Waseda station, so we constructed a pumping station which was located at a crossing with heavy traffic and was at a depth of 33m with high water pressure. Considering these conditions, we chose a non-open construction of a pumping station by PSS-Arch Method.
This paper shows and argues about the results of measurements of segments, curved steel pipes and support structures, and confirms an assumption obtained from measurements by 2D-FEM.
