摘要

This paper presents experimental results from tests on geosynthetic/geosynthetic and sand/geo-synthetic interfaces performed with an inclined plane apparatus designed in conformity with the European Standard prEN ISO 12957-2. More than 240 tests have been carried out, investigating almost all the interfaces that may occur in a landfill. The test results have been elaborated in order to make them comparable with direct shear tests results in a σ-τ plane. It is shown that the friction angles obtained by inclined plane tests are always lower than the ones obtained by direct shear tests for the same applied normal stress.
