This talk gives an overview of the experimental investigations on the interaction of GRS on the micro and macro scales carried out within the last years at RWTH Aachen University. The transparent soil technique was utilised in a novel testing apparatus to analyse the micro-mechanical processes at the geosynthetic-soil interface in terms of relative displacements, interfacial shear stresses and mobilised tensile load based on image correlation analysis. The macro-mechanical interaction of GRS walls during bearing-capacity failure was analysed in small-scale and large-scale tests. ***诚邀各位专家参会交流***  |
