Abstract:

Plane of 1 and 2 dams of water transfer of the CHAM SHIR dam are consist of 2 parts: the place of dam and the place of water transfer tunnel. In the excavated spaces inside the joint rock in the minimum dept currently kind of failure , falling the wedge from the roof or the walls behind the basement spaces. In analysis the stability of the tunnels that are excavated in joint spaces define, find the condition, dimension and analysis of stability of wedge is important. Discussed tunnel base on the done studies in geology and same condition of rock mass are divided to 3 part: A, B, C. with using the UNWEDGE software the condition of constructing the wedge with the rock potential are done. In this paper with making use of the software with the done analysis on the information of wedge and analysis the stability of wedge they designed the rock anchor for forbidden of falling the wedge.
