FEM Research on the Impact of Changsha Subway Construction to Wan Dai Hotel
For the Wuyi Square Station of Changsha Subway is close to Wan Dai Hotel, the construction process is simulated by FEM software Abaqus to research the settlement and distortion of the hotel building in this paper. To simulate the soil layers and diaphragm walls, compared seepage and stress are considered in the three dimensional elastic-plasticity model, in which the building is replaced by uniform load on the ground and horizontal supports are simulated by uniform load or moving distances. The vertical displacement of building foundation has been calculated, and recharging water has been simulated outside the pit. Finally, the control standards of building settlement are proposed to control the construction security of Changsha Metro Line 2.
