摘要

Motorway and railways, when situated in subsidence areas, are subjected to the multiparameterrnreactions of soil due to subgrade deformations. The essence of technical degradation ofrnsuch objects due to mining-induced subsidence entails changes in their functional and stabilitystrengthrnproperties. These changes take place within the structural system itself and, also in its subgrade.rnThe linear character of such objects creates a specific type of interaction between the subgradernand the elongated structure. The type of mining-induced contact reactions and the magnitudernof service loads determine the operating capability of structures under these specific conditions.
