INFLUENCE OF A SOIL-TRIP INTERFACE FAILURE CONDITION ON THE YIELD-STRENGTH OF REINFORCED EARTH

A comprehensive approach to the yield-strength of reinforced earth when considered as a macroscopically homogeneous material is presented within the framework of both the yield design and homogenization theories. In this paper, a more specific attention is paid to the case when a failure condition relating to the interfaces between the soil and the reinforcing strips has to be taken into account. A closed form expression of the corresponding macroscopic strength criterion of reinforced earth is given, along with a geometrical interpretation in the space of stresses. The analysis clearly shows a significant reduction in the overall strength of reinforced earth when compared to the case of perfect bonding. The consequences of such a reduction on the stability of some typical reinforced soil structures are then carefully examined by means of the yield design kinematic method using "rigid blocks" failure mechanisms.
