Experience with construction and operation of "Dinamo" stadium on fill soils in Minsk

Sitnikov, M. A.

Conclusions 1. During the preceding period (17 years) the fills were self-compacted until they attained the state of medium-density soils. 2. The main operation shortcoming of the structure was the intense formation of cracks in the walls, owing primarily to improper construction of the contraction joints. However, the cracks have not affected the operating adequacy of the structure, although they have made it necessary to repair systematically the weakened masonry and stucco. Some of the cracks are to be converted into regular contraction joints. 3. The major repair of the waterproofing coatings was dictated not only by their low quality but also, predominantly, by the differential settlement of the foundation beds. Obviously, the waterproofing elements are the weakest spot in structures built on heavily compressible soils; this fact should be taken into consideration in the projects. 4. The adopted construction measures for preventing large and differential settlements of the fills, namely, limitation of the pressure on the soil to 1.25–1.5 kg/$ cm^{2} $, application of additional compaction on the fills, and use of sand layers; intercrossed cast-in-place foundations, space-rigid superstructures, and contraction joints, were basically justified.
