Pre-tensioned Stress Coordination Function Analysis Of Bolt-cable Anchor Support In Rock Slope Engineering

In rock slope engineering, the slope of high thrust and the deformation of slopeengineering bolting requirements of the situation in difficulties, put forward the anchorand prestressed anchor combined support in rock slope engineering (actually existingdata and engineering practice shows that this type of retaining wall).Geotechnical engineering development on the slope of anchorage support theoryhas been relatively mature, geotechnical anchoring technique has a wide range ofapplication and practice in slope engineering, underground space engineering, tunnelengineering, mining and engineering. There has not been mature theory and basis withthe mixture of bolts and cables in the current slope engineering support, and alsobecause of the complexity of the mixture of bolts and cables supporting the problemitself and the particularity, for the study of the theory of the anchor rod and anchorcombined support is relatively lag, no matter from the mechanism of interactionbetween bolts and cables, design method, theoretical research, the current relevant dataare less. So there is a bad necessity on the study of the theory on bolt and anchor cablesupporting of the rock slope engineering.so study on pre-tensioned stress coordinationfunction analysis of bolt-cable anchor support in rock slope engineering is a veryvaluable academic problem.This paper is according to current mature geotechnical anchorage technologytheoretical analysis, experimental research and engineering practice, to mix in bolt andanchor cable in slope engineering of specific issues, in-depth analysis of themechanical characteristics of interaction between bolt and anchor cable,according tothe coordination between the bolt and anchor cable deformation condition,with theknowledge of using elastic mechanics analysis of force (gravity, anchor load and so on)on the slope deformation effect, and by using the finite element software UDECnumerical simulation analysis program, put forward a design method of of rock slopein a mixture of bolt anchor cable support.In the end of this paper,we will using thisanalysis method to calculate a more typical engineering example of a mixture of boltsand cables, introduces the specific content of the design method and applicationprocess, it can reflect the practicability in using of the this method.
