Abstract |
|
In this study regarding rock bolt in tunnel construction, the effect of rock bolts and shotcrete method on the stability of a tunnel below the ground as well as with in the mountains are studied. Rock bolts installed at the tunnel crown played a more important role in ensuring the stability of the tunnel roof than those installed at the tunnel sidewalls if the length and spacing were appropriate. Rock bolts installed with a certain inclination to the horizontal in the longitudinal section had the same effect as the rock bolts installed in the direction normal to the tunnel wall if the rock bolts of a certain length were installed with fairly dense spacing. This study review contains basic role of rock bolt techniques in tunnel construction. Also contains initial or construction cost at starting stage and maintenance cost, what kind of material, manpower and machinery required for construction of tunnel with this technique .for the different place which technique is better for saving time and cost of construction. |
