Conclusions

  1. 1.

    In the design of dock-type hydraulic structure with rigid connections between walls and continuous floor it is essential to take into account the reactive soil pressure on walls caused by temperature variations, which increases appreciably the stresses in these structures.

  2. 2.

    At the present time, only approximate methods are available for determining the subject reactive pressure, based on the hypothesis that it is directly proportional to structure deformations. However, proportionality-coefficient values for backfills have as yet little validity.

    It is desirable to continue development of more accurate methods for determining soil pressure on walls subject to temperature variations, treating the backfill placed in the spaces behind walls as an elastic, deformable medium.

  3. 3.

    In view of the considerable size of the reactive soil pressure generated on dock-type structures by temperature variations in many instances it is expedient, in order that loading be reduced, to terminate backfilling below full wall height.
