CONTACT Between POU_D_E and QUAD4 Possible?

Dear Community

I would like to analyse retaining wall-backfill interaction under static loading. As a preliminary analysis, I would like to model the retaining wall as a cantilever beam and the backfill in D_PLAN condition, modelled by Quad4 elements. Now I would like to know the following:

1. Can I mix POU_D_E element with QUAD4 ( in D_PLAN modelisation)?
2. Is it possible to define contact between the SEG2 boundary of the QUAD4 elements(lying at the soil-wall interface) and the POU_D_E element representing the retaining wall?

I have seen Contact example in Aubry's book, where contact is between 2D surfaces of 3D solids. I wonder, if contact between 1D elements as described above is possible to be defined in code-aster.

Thanking you all in advance.
