Abstract: The working principle of multipoint sine excitation system is simply introduce d.Through the dynamic property model test for Wan'an Project's guide wall,the in stallation of exciter and test method for oscillating mode are studied.The rela tive solvable methods on easily appearing effects of disadvantageous factors are proposed.And the modal parameters of self oscillation frequency,vibration mode and damp are precisely found. 
