| 摘要： | A somewhat unusual extension of the standard direct shear test was presented. Hot and cold conditions were presented herein. Clearly, the geosynthetic interfacial friction can be affected by temperature extremes. However, we were surprised that there was not significant reduction in shear strength at the extreme temperatures for the samples we tested. This was noted not only by the small differences in results but also by the minor changes in surface conditions post-test. We were pleasantly surprised to see so little change in the peak frictional response for both the smooth and textured geomembranes. |
