With FLAC3D Simulating Analysis the Rock Stability by Stretching Anchor Cables Reinforce on the Reservoir Dam Abutment
By studying the geological structure and seepage character, in YanJin bridge reservoir region the harmful geological structure had been reinforced with anchor cable. To establish constitutive law and yield-dstroy critertion of anchorage zone, working state of anchor cable was simulated with FLAC software. With two states of no seepage and Stress-seepage coupling in the reservoir, the anchor cables and the state of the dam abutment rock was computed, but the mechanic character of the harmful geological structure and anchor cable was studied. The deformation stability was accurtely appraised in the high slope rock of dam abutment, by comparing with the state of unreinforce rock, analysing the loading effect of the structure face in anchor cables and the stability regular of slope rock . The computing results have the greater practical values for the reservoir work.
