抄録

In previous paper, the author culculated stress distribution around the two parallel excavated horizontal circular tunnels. In this paper, the author tried to find the stresses around two tunnels, which excavated parallel, but are vertically doubled. With the same method as before, the author culculated the change of stress distribution according to the change of l. l means as follows: l=ζ/2r<BR>Where ζ is the distance between two tunnels, r the radius of these two tunnels. The stress distribution according to l changes as we see in Fig (4).
