Критикуемые реологические уравнения состояния построены для неубывающих режимов нагружения, и при разгрузках их действительно применять некорректно. Кроме того, сомнения опираются на пресловутую диаграмму σ–ε с ниспадающей ветвью, которая может быть построена только при замере в опытах напряжений по заданной деформации. При построении реологических уравнений используется другая диаграмма. Принципиально проблема решена в предложенной А.А. Гвоздевым и развитой К.З. Галустовым двухкомпонентной теории ползучести, и этим окончательно закрыт вопрос о применимости принципа. В этой теории деформации делятся на частичные по принципу их обратимости. Предложен способ такого разделения с возможностью использования существующей нормативной базы, который позволяет существенно адаптировать теорию к потребностям практики.</p></abstract><trans-abstract xml:lang="en"><p>In scientific publications devoted to the theory of creep, there are doubts about the correctness of the superposition principle, which does not work during unloading. The criticized rheological equations of state are constructed for non-decreasing loading modes and it is really not correct to apply them when unloading. In addition, doubts are based on the notorious diagram σ–ε with a descending branch, which can only be constructed when measuring stresses in experiments for a given strain. When constructing rheological equations, a different diagram is used. In principle, the problem is solved in the two-component theory of creep proposed by A.A. Gvozdev and developed by K.Z. Galustov, and this finally closes the issue of the applicability of the principle. In this theory, deformations are divided into partial ones according to the principle of their reversibility. A method of such separation with the possibility of using the existing regulatory framework, which makes it possible to significantly adapt the theory to the needs of practice, is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бетон</kwd><kwd>ползучесть</kwd><kwd>принцип наложения</kwd><kwd>мера ползучести</kwd><kwd>реологические уравнения</kwd><kwd>нелинейность деформаций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete</kwd><kwd>creep</kwd><kwd>superposition principle</kwd><kwd>creep measure</kwd><kwd>rheological equations</kwd><kwd>non-linearity of deformations</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Назаренко В.Г., Звездов А.И., Ларионов Е.А., Квасников А.А.
