REVIEW OF STABILITY STUDIES ON GEOMEMBRANE

The research advance in the factors and mechanisms affecting the stability of geomembrane and its evaluation index of stability was summarized. The research on the stability of geomembrane used in the past few years was generalized. The actions of free radical oxidation were narrated from the aspects of UV degradation, biological degradation and oxidative degradation, according to the research actuality of the degradation mechanism of geomembrane. The research methods and the application of spectrometry, thermal-dynamics and rheology in the field of geomembrane stability were drawn. Several factors affecting the oxidative degradation of geomembrane were summed up, and the research actuality and application of antioxidant on the degradation of geomembrane were reviewed.
