A basic physical experimental research of lateral passive pressure is in progress at the Institute of Theoretical and Applied Mechanics. The research is composed of three doubles of the same experiments with three basic retaining wall movements: rotations about the toe or top and translative motion. A double of the same experiments E5/0,1 and E6/0,1 with passive pressure and pressure at rest during wall rotation about the toe was carried out in 1st half 2012 and the 2nd one (E6/0,1) was finished in the early 2013. Both experiments together should prove a real behaviour of noncohesive mass acting on moving wall. The behaviour appears distinct from a theory of EUROCODE 7-1 contemporaneously used. Each of experiments has brought a huge data quantity. The paper shows strains of both masses, i.e. deformations and slip surfaces of the experimental sandy masses.
