| Abstract: | In this paper, the influence of prestress tension of Si Bao Sewage Treatment Plant's concrete shell structure has been studied experimentally. The effective stress is determined and the reliability on prestress tensile technology has been studied. The coefficients taken from standard and construction have been compared. The technique to control tensile force and tension for design use has been proposed. |
