13th International Conference on Fracture June 16–21, 2013, Beijing, China -7- along the north-east direction [5] ，and the fact of the happening of Ms6.3 Hejian earthquake on March 2, 1967 proved the prediction of Prof. Li Shi-Guang. This shows the interaction between earthquake faults. 3.1 The static fracture analysis We take the physical model for the interaction between co-linear faults shown in Fig.4 Fig.4 Model for co-linear faults in North China Block The static fracture analysis on the interaction between co-linear strike slip faults can be based on the equation (1) and (2), but the boundary conditions are given as follows (23) The complex analysis is still effective for the present problem, but we should use the following conformal mapping (24) (25) != "+i# $= 1!e!!a/H 1!e!!(a+L)/H !=e!"L/H (26) and find the solution !!(") = 2!H !2 [ "#M (1+!)2 +!"(1!!)2 ! !A (1+!)2 +!(1!!)2 ]! 2!H !2 i!(1!!)(1!! 2) [(1+!)2 +!"(1!!)2][(1+!)2 +!(1!!)2] !ln i !! 1!i!
