Construction of a tailings pond on a thick stratum of made ground

Conclusions

• 1. For the first time in Soviet engineering practice retaining earth embankments were constructed on a thick stratum of inhomogeneous rock-free made ground of the inner spoil heap of an operating opencut mine and were put into operation in 1975.

• 2. Construction of the embankments on a thick stratum of rock-free made ground is possible when the following measures are taken: flooding and overloading the foundation, construction of drainage intersecting the seepage flow in the embankment body and foundation, equipping the structures with a special system of monitoring instruments, and organization of constant supervision of construction and operation.

• 3. The design and construction of retaining embankments on made ground should be preceded in each case by full-scale investigations of the deformations of the foundation and change in its physical and mechanical properties under the effect of flooding and overloading and by establishment of the flooding time and necessary degree of overloading.
