摘要：

Using an Internet-based survey system, the precision of the visual comparison technique in estimating the Joint Roughness Coefficient (JRC) value was examined. A survey of people involved in geotechnical engineering was carried out over the Internet. The survey was set up on 23rd November 1998 and as of 28th July, 2000, 125 estimations were made for Profile A, 124 for Profile B and 122 for Profile C. Overall, the study clearly demonstrated the effectiveness of the Internet as a medium for carrying out surveys of this type.
