I use "add vector layer" to import my dxf file in QGIS. But, when I open the attributes tables of the layers (point, polyligne, polygone), I see that the majority of the attributes (color, …) of the layers has disappeared !!! Do you have any idea of this problem ?

There is nothing wrong in your file. I opened your dxf file from Add Vector Layer without problem using QGIS 2.14.8 and QGIS 2.18.0. Here is the output:
I also used the 'Another DXF Importer / DXF2Shape Converter' Plugin and it was opened without any problem. Here is the output also:
Try to use update your QGIS to the latest 2.18.0 or use QGIS 2.14.8 LTR (long term release). It may solve your problem.
Try using the Set Z value tool in Processing Toolbox > Vector geomoetry instead of Grass.
Use the icon to the right of the Z Value input and click Edit to add an expression. For the expression just write "ELEV".
Then when you are exporting the layer to DXF make sure the Include z-dimension box is checked, if it isn't then set the Geometry type to LineString and then check the box.
