| Abstract: | A discussion was made on standard for grouting at starting and ending of the construction. The initial and ending grouting standard was developed according to permissible drainage volume of tunnels, and single hole ending grouting standard was developed according to final grouting pressure and grout volume. An empirical equation was raised for single hole ending grouting standard. |
