| Abstract: | According to the specification of through accuracy, the tunnel control network in and out of the caves is de signed and the relative through error is estimated. The data result shows that the estimation satisfies the tolerance specifi- cation and this tunnel control networlc is feasille. Some suggestion atont how to improve the through accurary is given. |
