The use of geosynthetic materials in special engineering geological conditions of the Far East

The design of a variable hardness is developed for preventing deformations in the line facil-ities built on sections with different stability. The results of geotechnical modeling are presented with the example of federal Vladivostok-Nakhodka road. This highway is constructed in the harsh environments and complex engineering-geological conditions on seasonal freezing soils. The sections with different stability are located there. The design includes installation of geosynthetic material layers. The amount and location of the geogrid layers depends on the base stiffness. The structural behavior modeling with the geotechnical software complex «FEM models» gives a design assessment. Some constructional measures are taken as a result of the modeling to provide an exploitation reliability of the highway engineering solu-tions
