| Abstract: | This paper puts forward the design argument of the scheme of fast construction applying hydraulic shrinkage-compensating concrete for the upper coffer-wall of a station. In the paper, dealt with are mainly the following- the blocking of concrete placement of the coffer-wall, expanding prepressing stress and coffer-wall temperature stress, calculation of the opening of joints and the analysis of crack-resisting effect and the performance test and contrast choice of hydraulic shrinkage-compensating concrete. |

| Keywords: | shrinkage-compensating concrete self-volumetric deformation prepressing stress temperature stress sudden drop of air temperature |
