When i want to mesh a assembly geometry by use of the ANSYS-ICEM, i firstly repair the geometry. so the gemoetry is as follows and the bule lines is not good .
SO do i must repair the blue lines ?

Blue lines just means "multiple edges". Basically, there are "more than 2" edges within the topology tolerance of that edge. It removes the others and keeps just 1. It may be fine if that is what you were expecting... It looks like you have walls that "T" connect with the surface. In which case, blue edges are fine (the three surfaces meet along the blue edge).
There are certain solvers that can't handle multiple edge T connections, but major commercial solvers don't mind at all.
Another possibility is that you have a thin surface and it is collapsing it along the surface to get the blue line... This is not what you want. If this is the case, measure to see what your smallest surface size is (that you want to capture), then reduce your topo tolerance to below this and try again.
Blue lines are a warning to look closer and make sure they are where they should be.
