SECONDARY SEDIMENTATION OF UNDERGROUND STRUCTURES IN THE WATER-CONSISTENT MASSIVE WITH BASIS GROUND DEFORMATION WITH SLIP PRISM FORMATION
Journal Title: Вісник Кременчуцького національного університету імені Михайла Остроградського - Year 2017, Vol 1, Issue 105
Abstract
Purpose. Definition of nature of the soil basis deformations development, taking into account the interaction of structural elements in the secondary settling down of the underground facility. Methodology. Laboratory studies on the precipitation of the sandy loam samples provided, taken from the alluvial massif in conjunction with mathematical modeling of the process of settling underground facilities. Results. After the initial subsidence, under the aggregate of engineering-geological influences, there is a redistribution at the level of structural elements, which leads to the intensi- fication of secondary sedimentation of the underground facility. As a result, the distribution of the stress-strain state of soils around the underground facility changes. Originality. For the first time, the influence of the sand mass water saturation and an additional load from the movement of trains on the intensification of secondary sedimentation of shal- low laid underground facilities has been determined. Practical value. As a result of periodic water saturation of soils there is an intensification of secondary sedimentation of underground facilities, which can have undamaged nature of the process should be taken into account when designing and operating transport communications.
