Abstract: In order to meet the need of the actual rock engineering, the methods are required to verify the result of the 3-D discontinuies network modeling. One method is to compare the figures between the section of the numerical model and the sampling window of in-situ model. The other method is to verify the data set of the numerical model using field data. When the modeling results are verified to have a good precision, They can be considered effective, and can be applied into the actual rock engineering.
