between RQD& lugeon) are satisfied, but in other 

![0_image_1.png](0_image_1.png) zones, the said rule is disregarded. To finding out of the background on these major zones, we refer to the clustered data set by 2D SOM 
with 7*9 weights in competitive layer (figure 10-c), on the first set of the attributes. The clustered and graphical estimation disclose suitable coordination, relatively. For example in figure 13-b, we have highlighted three distinctive patterns among lugeon and Z, RQD, TWR. One of the main reasons of being such patterns in the investigated rock mass is in the definition of RQD. In measurement of RQD, the direction of joints has not been considered, so that the rock masses with appropriate joints may follow high RQD.
