AN EXPERIMENTAL STUDY OF REFRACTURE ON HEALED FAULT

Zhang Zhi Wu Kaitong(Center for Analysis and Prediction, State Seismological Bureau, China) Geng Naiguang Li Jihan Liu Xiaohong(Institute of Geophysics, State Seismological Bureau, China)  
In order to model healed fault, standard columnar sample is made from Jinan gabbro, which is sawed with various angles and cemented by epoxy resin. Under the uniaxial stress, healed fault is refractured. It is found that precursor deformation of healed fault, which is refractured, the regular change of acoustic ratio and the bvalue before rupture are similar to the complete samplin some conditions and to the stagger of original faults in sample in other conditions. The angle between fault plane and main stress as well as the degree of fault being healed, is the factor affecting the refrac ture of healed fault. It shows that the problem ofhealed faults is very important in study of seismic activity.
