| Abstract: | In view of the characteristic which the temperature contraction cracks of mass concrete is not easy to control, the paper analyzed that what cause the temperature crack in bridge mass concrete by carrying on site construction management to piers of a continuous beam bridge. The paper also uesd a series measures which combination of the choice of raw materials and extra adulterating agent, temperature detection monitoring, circulating water cooling to inspect and handle of the mass concrete cracks, and it achieved good results. |
