Technology of hydraulic filling of structures with slope protection by a silted gravel covering

Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    On the basis of a generalization of construction experience and experimental investigations a new technology of hydraulic filling of structures of a flattened profile with protection of the upstream slope by a silted gravel covering is recommended. Siltation of the covering is accomplished during layerwise hydraulic filling, and in certain cases the gravel covering can serve as an embankment during hydraulic filling.

  2. 2.

    Siltation of the covering increases the strength and wave resistance of the upstream slope due to cohesion of clay and silt particles with the sand component of the covering and makes it possible to reduce the thickness of the gravel covering by 20–30%.

  3. 3.

    For designing the technology a calculation method is recommended which consists in determining the steepness of the slope from the nomogram in Fig. 4, thickness of the coating by Eq. (3), and time of filling the pores by Eq. (6).

  4. 4.

    The developed technology effects a considerable economy due to reducing the thickness of the gravel coating as a consequence of its siltation.
