| Abstract: | High density polyethylene (HDPE) geomembranes tend to wrinkle and deform as temperature increases, which in turn deteriorates the contact conditions and hydraulic performance of landfill composite bottom liner systems. To clarify geomembrane wrinkle behavior under combined temperature and overburden pressure effects, this study employs the energy conservation principle using a simplified two-dimensional model to theoretically derive and analyze: (1) wrinkle formation due to temperature rise without overburden pressure, (2) wrinkle formation due to temperature rise with overburden pressure, and (3) changes in existing wrinkles caused by pressure. Comparative analysis of theoretical predictions with laboratory-scale model experiments validates the applicability of the energy method for characterizing geomembrane wrinkling behavior. Furthermore, the combined effects of temperature and overlying soil pressure on geomembrane wrinkles are quantitatively elucidated by model calculations. This work provides a theoretical basis and a reference for understanding the formation mechanism of geomembrane wrinkles and for developing corresponding engineering preventive measures. • The geomembrane wrinkle under combined action of temperature and pressure is analyzed by the energy conservation method. • Indoor model tests of geomembrane wrinkling are conducted to validate the theoretical method. • Quantitative influence laws of temperature combined with overlying soil pressure on geomembrane wrinkles are studied.
