Rheological calculations of the foundation subgrade by the example of one of the landslide sites of the far eastern railwa

Abstract

The safety of railway transport is affected by the quality of the superstructure, which is closely connected with the condition of the roadbed. In areas with a high precipitation and complex terrain landslides and local flow, causing deformation of the subgrade are possible. From here relevant is the prediction of the rheological state of landslide-prone sections of the railway with the change in humidity of the base soil subgrade. In the article on the basis of the theoretical developments of the authors an example of the rheological calculation of one of the landslide sites of the Far Eastern Russian railway is considered. There is a fairly good convergence of settlement data with the results of independent observations of resistance and deformities of the earth canvas, which allows us to recommend the developed developments for practical application. There is a fairly good convergence of calculated data with the data of independent observations of the stability and deformations of subgrade, which allows us to recommend the obtained developments for practical applications.
