Design of foundation pit retaining structure of three door station
ABSTRACT:This graduation design is pided into two parts, the first part is the Shanghai metro line three, ten station foundation pit retaining structure design; the three part is the second road station foundation pit construction organization design. In the first part three avenues station foundation pit enclosure structure design, according to the three door station within the precincts of the engineering geological and hydrogeological conditions and the surrounding environment condition, thus in the comparison of many schemes selected by underground continuous wall as retaining structure of foundation pit, and considered by the economic and technical considerations, the choice of steel as the support system of the foundation pit support, also on three channels station foundation pit enclosure structure stability checking, according to the calculated results of the internal force of reinforcement, of foundation pit precipitation treatment and reinforcement. In the second part of the three channels station foundation pit construction organization design, according to the three avenues station foundation pit construction scheme of the foundation pit and the surrounding environment, the construction of the foundation pit to make corresponding preparations, construction general layout, the preparation of foundation pit project schedule plan and management measures, and write the quality, safety and civilized construction management measures.
Keywords: foundation pit; underground continuous wall; steel support ; construction organization; dewatering of foundation pit; Stability checking
