Zusammenfassung: | Purpose. The article is devoted to stabilization parameters determination of reinforced railway bed. At the present time, the railway plays the leading role in transport system to ensure the needs of freight and passenger traffic. In modern conditions railway operation concentrates on ensuring the necessary level of track reliability, including the roadbed, this is one of the main elements of road structures. The purpose of this article is the determination of basic parameters of stress-strain state to stabilize the soil subgrade embankment by reinforced materials. Methodology. To achieve this goal the following tasks of researches were solved: the effect of reinforcing layer of geomaterial on deformation properties of soil subgrade in various design of strengthening was investigated, the distributions of stresses in the subgrade were determined, reinforced of geomaterials under state load. Experimental studies to explore the nature of the deformation model subgrade at various degrees of stress were carried out. Findings. The analysis of the results of performed experimental and theoretical studies permitted to do the following conclusions. In conducting researches determined the distribution of stresses in the subgrade reinforced geomaterials under static load. The complex of experimental studies allows exploring the nature of the deformation model subgrade at various degrees of stress. Originality. On the basis of the theoretical studies have been regarded the problem of determining the stress-strain state of subgrade reinforced geomaterials by measuring stresses in its application for step loads. Practical value. The practical value was presented by the results of evaluating the effect of reinforcing way for changing the stress-strain state of subgrade.
Мета. Стаття присвячена визначенню параметрів стабілізації підсиленого залізничного полотна. В даний час залізниця відіграє ключову роль у забезпеченні потреби пасажирських та вантажних перевезень. У сучасних умовах експлуатація залізниць сконцентрована на забезпеченні необхідного рівня надійності колії, в тому числі земляного полотна, яке є одним із ключових елементів дорожніх конструкцій. Мета цієї статті полягає у визначенні параметрів напружено-деформованого стану для стабілізації грунта земляного полотна насипу підсилюючими матеріалами. Методика. Для досягнення цієї мети було вирішено такі завдання досліджень: вивчено вплив армуючого шару геоматеріалу на деформаційні властивості грунтового земляного |
