are very important to underground cavern design and construction. Lots of cost
materials and efforts are needed if field test is done. Sometimes
the result of field test is not very good. In this situation
application of the inverse analysis theory can overcome the disadvantages that the field test has. Using this theory
displacement that can be got easily by field test
is used only to calculate the needed parameters. There for the direct displacement inverse analysis is used to calculate the rock parameters for Shibeiling tunnel.
