Abstract:

Today, using the DOZ rocks are developed because of minimum expensive and effective applied of that stability of rock mass special in tunneling. The other good information about them is their easy constructing and expand using of them in each place with the different erection. This paper introduce the mathematic models in design of them try to survey the operation of them in around walls of tunnel and strength effect of them as a traverse element. Injection kind of them is more important from the others and distribution of strain around them is surveyed. In this research the elast plastic monitoring of them and rock mass , strain distribution around that and effect of erecting that on the parameters of rock mass are modeled with FLAC software. Constructed methods has central symmetry and are construct on the rock with 10 meter diameter and 12 numbers of them are used with 25 meter diameter and the length of 5.6 meter that are erected as a symmetry kind in around the tunnel. Analysis is done on 2 kind of ROCK DOZ. The comparison are done between the excavation of tunnel in 1 part with excavation in 4 part. In the end find models from numerical method are compared with the Inderatarna and Kaiser methods
