title: Development of innovative designs of drainage pipes that increase their stability in difficult geotechnical conditions
abstract: Studies of drainage pipes with different cross-sections have been carried out. Designs of drainage pipes with cross sections constructed using cycloid shapes have been developed. Analytical and model studies have shown increased stability of the arches of these pipes. The latter makes it possible to achieve a sharp reduction in the risk of loss of stability of drainage pipes under complex static, seismic and dynamic loads.
