【Abstract】 In the paper,the travel law of seismic wave which is excited by explosive shock,and the relation between the vibration signal of ground and electric signal recorded by instruments are discussed.On the basis,we expounded the principles of measurement of vibration effect,the methods of correcting instrument system and removing the effect of instrument from observed recordings,and we measured the vibration effect in main factory part of one power station which is being built in Yunnan province.Finally the problems which should be cared during detecting vibration are discussed.更多还原
