| Abstract: | The souls of concrete are firmness and endurance.Cracks of concrete affect construction quality.The true stress state of hydraulic concrete structure is very complex.There exists much more difference between stress state in construction and design.The reasons to difference include construction process,temperature stress,structure type,foundation deformation,materials and its mechanical property etc.Based on the crack mechanism,crack prophylactico-therapeutic measures are put forward by using emulated temper... |
