Conclusions

  1. 1.

    Full-scale investigations show that stresses in the concrete of massive gravity dams are the result of the total action on the structure of external loads, weight of the concrete, and temperature-moisture changes during the construction and operating periods. The stresses occurring during the construction period are “frozen in,” changing only slightly during operation, depending on changes of the external load and temperature conditions.

     
  2. 2.

    To compare the actual stresses with the calculated (determined in conformity with the existing regulations) it is necessary to divide the total deformations measured in the concrete into components, isolating that part which is caused by external loads on the structure. Such division can be done by the method of statistical analysis of the measured deformation.

     
  3. 3.

    The impossibility of taking into account by calculation methods a number of factors influencing the stresses and strains in a dam is the cause of some divergence between the values of stresses produced by hydrostatic pressure obtained on the basis of a statistical analysis of deformations and the calculated stresses. Such factors include, in particular, opening of joints in the downstream and upstream faces of the dam, effect of the steelreinforced-concrete conduit on the static work of the structure, etc.
