Metoda uproszczona oceny odporności budynków na wpływy od eksploatacji górniczej – artykuł dyskusyjny
Artykuł podejmuje próbę dyskusji nad metodą uproszczoną oceny odporności budynków na wpływy od eksploatacji górniczej. Zwraca uwagę na kilka problemów związanych z interpretacją i sposobem stosowania wspomnianej metody oraz zawiera propozycje pewnych modyfikacji punktacji. Podejmuje również problem oceny obiektów podzielonych na oddylatowane segmenty.
Concerning the issue of the resistance of buildings to mining activities, this paper refers to the most popular simplified method as contemplated in the title thereof and developed by the State Mining Authority in the 1960s, and sometimes referred to as the localised method. Selected problems and issues relating to using this method in practice have been subjected to analysis in this article, namely: the lack of differentiation between the occurring horizontal tensile deformations and horizontal compressive deformations, the feasibility of evaluating the buildings constructed using new technologies, and/or with special bracing reinforcement, the soil load-bearing capacity analysis, and the evaluation of buildings located in the areas where no mining operations have been performed. Another problem discussed herein is the measurement and design calculation of expansion joints in segmented structures. This paper proposes a modification of the method concerning the complementary table, the score rating of specific building length dimensions, and the rating of the deployed building reinforcement. As repeatedly emphasized in the literature, the contemplated simplified method is a statistical tool only and will always be encumbered with a certain error margin. Beyond any doubt, it is necessary to consider this approach when evaluating a large number of buildings within a relatively short time. However, the reliability of the analysis warrants the typing of buildings that feature dubious structural and material solutions or other unclear issues, followed by an evaluation of, for instance, 10% of the investigated structures using an expert-oriented approach.
