| Abstract: | Taking the high strength massive concrete of base of thin-walled hollow pier as the research target,the temperature and stress in concrete under different constructions conditions are simulated by computer technology and the anti-cracking safety efficiencies are also studied.All these offere the theoretical basis for the temperature cracking control in the concrete. |
| Keywords: | high strength massive concrete temperature stress anti-cracking efficiency |
