Abstract
Reinforced retaining walls were used on the overpasses of the Central Ring Road. To reduce the sedimentation of the base of these walls, to reduce the time of consolidation of the base, the transformation of soil properties by reinforcing vibro stone columns was used. In order to obtain an optimal result for the transformation of the properties of the base soils, increasing the reliability of the reinforced structures, comparative calculations were carried out with the variation of the parameters of the reinforcing elements. The method of quality control of the device vibro stone columns is improved.
Highlights
A promising method of strengthening weak soils when creating artificial structures is the transformation of the properties of the base with reinforcing vibro stone columns
MSE-walls were used on the overpasses of the Central Ring Road
The construction sites of the Central Ring Road (SKAD) overpasses are characterized by the presence of highly compressible soils
Summary
A promising method of strengthening weak soils when creating artificial structures is the transformation of the properties of the base with reinforcing vibro stone columns. This method is relevant in the design of highways [1,2,3]. The regulatory documents do not cover in sufficient detail the issue of the maximum values of the deformations of the base for MSE-walls, only the possible mechanisms of destruction are considered. For example, in the ODM 218.2.027-2012, the requirements for the deviation of the front surface of the MSE-walls are given, but there is no tolerance for the maximum precipitation of the base
