Study On Calculation Model For Bolt Stress Of Rock Slope

There is a huge number on rock slopes, slope disstability will cause seriousconsequences. The bolt axial force specification proposed force of rock slope is evenlydistributed, or close to the uniform distribution by tandardized method,which the actualtesting and simulation is very different. It is necessary to propose a new computationalmodel based on the slope and anchor bolt force coordination deformation mechanism.When rock is good and there is no camber slope structure surface, the slope rock isregarded as isotropic elastic material, using elastic mechanics, the displacement of theslope will be studied under the effect of the bolt axial force and gravity heap load.Onthe basis of displacement of the analytical solution, Takeing into account the analysis ofin-depth slope and bolt deformation coordination mechanism, considering the sloperetaining economy, a new rock slope bolt axial force calculation model: axial force andbolt deformation related to the slope,is proposed, It is knowed that the displacement ofthe top of the slope is bigger than the bottoml, nearly twice the height of the slope alongthe curve distribution.then UDEC program,a numerical simulation programe is used toconfirm the correctness of the calculation model. Finally, with specific examples ofproject, compared the method studied with tandardized method on the the rock slopebolt axial force by force calculation model, the similarities and differences are studied inthis paper.
