Ensuring Stability of the Earthbed in Conditions of Over-Watering on Weak Soils in the Karaganda Region

The issues of ensuring the stability of the roadbed of railway transport tracks in conditions of waterlogging and weak soils are considered using the example of the Karaganda region. Given the peculiarities of the geological and climatic conditions of the region, high humidity significantly reduces the strength characteristics of the foundation, which leads to deformations and disruption of the geometry of the railway track. An analysis of the types of soils typical for the region, as well as their granulometric and physical-mechanical properties, is carried out. Particular attention is paid to the use of bitumen-containing materials and other modern strengthening technologies that ensure an increase in the bearing capacity and water resistance of the foundations. The paper presents the results of numerical modeling of the stress-strain state of the structure, allowing to assess the performance of the roadbed under vibration loads arising from the movement of rail transport. The proposed engineering solutions are aimed at increasing the reliability and durability of railway transport infrastructure facilities in complex hydrogeological conditions
