Polymer and Geocomposite Impervious Screen Reliability Assessment

Abstract

The article examines the operational reliability and technical efficiency assessment of polymer (geomembranes) and geocomposite (bentonite mats) impervious channel coating developed designs. Criteria for impervious channel screen reliability and technical efficiency are proposed based on the domestic and foreign experience generalization in the composite materials use and conducted efficiency studies in terms of water permeability, strength, efficiency, and durability. Two options of developed highly efficient structures for polymer and geocomposite channel linings are presented. The graph of change in screen failure-free operation probability was obtained based on the impervious screen failure-free operation probability calculation results, depending on the survey areas and the failure amount.
