%X With the three-dimensional deformation survey system composed of the high accuracy lightwave electronic tachometer combined with reflecting film,the three-dimensional displacements at fault F7 and slate with sandwiched Phyllis section of Silurian have been tested and analyzed in Wushaoling tunnel.Meanwhile,the response characteristics and deformation character of excavated strata of tunnel are presented through three-dimensional deformation revelation that is developed by European scholars.Result shows that the displacement vector orientation trend line at the place,which is 1.0 time of the tunnel diameter or less from working face,can be used to reveal the distribution and change trend of rock mass stiffness at certain region,and it can predict the change trend of soft and hard rocks or unfavorable geological structure at excavated strata.At present timei,t is still under its initialization for underground construction engineering,and the information related to displacement is analyzed,which is obtained by exaction with that of the practical geological condition of surrounding rock.With the help of other geological forecast facilities or methods,the geological conditions of the unexcavated ground around cavern can be properly predicted.
