Abstract
Background: Long-term deformations of hydraulic structures on weak foundations and swamps lead to the need to develop new construction technologies that increase the bearing capacity of soils. The existing standards for the design of railways and highways are mainly focused on ensuring the safety of the roadbed at the operational stage. Meanwhile, the risks of loss of stability and stability of road sections also arise at the construction stage, especially when powerful heavy construction machinery and equipment are operating.
Aim: Formation of a technical and technological system functioning on the principles of direct and feedback between the characteristics of the constructed roadbed and the parameters of construction equipment to ensure the safety and quality of work.
Methods: Technological regulation of loads and impacts of construction machinery and equipment during the strengthening of the foundation and the construction of embankments of the roadbed.
Results: The composition of the complex technology and the regime of regulation of construction loads have been developed to increase the bearing capacity of weak soils at the base of the roadbed of railways and highways. The features of geotechnical monitoring for the directed improvement of the strength characteristics of soils during the construction period are determined. The expediency of technological regulation of loads and impacts of construction machinery, equipment during the construction of the roadbed is shown.
Conclusion: The complex technology of increasing the load-bearing capacity of the weak foundation of the roadbed consists in the consistent application of regulated modes of intensive impact on each layer of the foundation with the maximum permissible load during geotechnical monitoring.
