description: The subject of the graduate qualification work is: "Calculation methodology of the embankment reinforced with volumetric geogrids". The work is devoted to the issues of computational substantiation of reinforcement of low embankments and zero level with volumetric geogrids, with weak water-saturated clay soils in the embankment base.
The research set the following goals:
1.Review of modern methods of embankment reinforcement.
2. Analysis of design models of embankment reinforcement in weak soils with vol-ume geogrids.
3. Modeling of structural options for reinforcement of the embankment on weak soilsusing the volumetric geogrid.
4. Development of the calculation method of the embankment strengthening and sta-bilization by the volumetric geogrids, by giving an example of the calculation ac-cording to this method.
The concept of EWBRG (The road embankment weak base is reinforced by geogrids) model was introduced. Based on the Mohr-Coulomb strength condition, the cal-culation method was derived and the numerical simulation algorithm was developed in PLAXIS 2D Model EWBRG program. In the program of the complex calculation of the initial stress state of low embankments on weak water-saturated clay soils without rein-forcement and with reinforcement by volume geogrids was performed. As a result of numerical modeling, the nomograms for calculating the structure under the condition of shear stability were built. The obtained dependencies are precisely enough approximated by polynomials of the third order (R2=0.99...1).
