Approach to evaluating the change of properties of the geosynthetic material used to stabilize the marine landscape slopes

Changes in the properties of geosynthetic materials (geomats) used in coastal protection structures that protect the high coast from erosion, landslide and talus processes are analyzed. The proposed approach includes the selection of a representative set of sampling points for geomats, which takes i...

Description
Summary:Changes in the properties of geosynthetic materials (geomats) used in coastal protection structures that protect the high coast from erosion, landslide and talus processes are analyzed. The proposed approach includes the selection of a representative set of sampling points for geomats, which takes into account various exposure conditions, conditions for the extraction of groundwater or in dry places, under the direct influence of the wind or in continuous grass cover, and other local operating features. In the process of cameral work with samples of the geomat, taken at the sampling points, it was proposed to assess the degree of degradation of the geomat, used to keep the slope from breaking, by the value of the breaking load of individual polymer filaments, while assessing the degree of microdamage of the material under study. Objective monitoring of microdamage of filaments is carried out by computed X-ray tomography. Using two geomat sampling as an example, the effectiveness of the approach is shown. Regular monitoring of the properties of geosynthetic material will provide an estimate of the residual life of the shore protection structure, a selection of recommendations for its repair and optimization.
