Temperature load is one of the main load of arch dam , timely and accurate grasp of arch dam during the construction phase of the temperature field and thermal stress field , has important implications for dam construction . Therefore , the concrete arch dam construction of the temperature and stress field simulation has become an important research topic . Papers based on the characteristics of the concrete arch dam construction , the proposed construction of temperature and stress field simulation analysis conducted its international general-purpose finite element software , and software related to the combination , considering the changes in the outside temperature , heat of hydration of cement the actual impact of different pouring temperature changes with age , and stratification , proposed simulation realization process . Concrete arch dam on the basis of the above work , the paper according to the simulation of the construction process of the construction schedule given to calculate the temperature and stress field of the construction period , and made ??a comprehensive study of its distribution and development of the law , draw some useful conclusions . Grams Tian arch dam is located in Yunnan Province , an arch dam . The paper made ??a simulation of temperature and stress field in this concrete arch dam construction period , come pouring temperature , heat of hydration of concrete , and the outside temperature affect the temperature field of construction period great, the slower the dam lower part of the cooling process , etc. Conclusion for arch dam temperature control measures taken in the construction of the corresponding reference .
