A new method of equivalent pre-stress is suggested by used of methods of equivalent strain and temperature according to different working mechanisms between free segment and consolidated segment of anchor cable. The mechanism on reinforcement of pre stress anchor cable is simulated by finite element. It is concluded that the axial stress and displacement of consolidated segment tends to be initiated gets to decrease with the increase of depth. The shear stress of the out end of free segment increases rapidly and arrives at the biggest value, then decreases slowly with the increase of depth. The stress and displacement of rock is distributed in axi-symmetric mode with anchor cables. The concentration zone in shape of a funnel is formed at the out anchor head. The concentration zone in tension is formed at the inner consolidated segment. The surrounding rock at consolidated segment is the interface in shape of paraboloid between the compression zone and tension zone.This document explains and demonstrates how to prepare your camera-ready manuscript for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. The text area for your manuscript must be 17 cm wide and 25 cm high (6.7 and 9.8 inches, resp.). Do not place any text outside this area. Use good quality, white paper of approximately 21 x 29 cm or 8 x 11 inches (please do not change the document setting from A4 to letter). Your manuscript will be reduced by approximately 20% by the publisher. Please keep this in mind when designing your figures and tables etc.
