In previous paper, the author culculated stress distribution around the two tunnels, which excavated horizontally parallel and the other case vertically doubled.
In this paper, the author dealt with again the same problem and tried to find the stress distribution in the following case:
(1) two circular tunnels have the same radius, but not excavated horizontally parallel or vertically doubled.
(2) two circular tunnels have not the same radius, one is large, the other small. In this paper, we can see the great compressive stress at the near side of those two tunnels.
