Influence of Frequency of Blasting Seismic Wave on Critical Vibration Velocity of Underground Chamber

摘要：

The wave function expansion method is employed to analyze the interaction of blasting seismic wave and the adjacent underground chambers, the stress expression and displacement expression of circular underground chambers under the action of blasting seismic wave are deduced, the stress and displacement distribution of surrounding rocks mass are presented under the condition of the different frequency of blasting seismic wave and different rock mass. In terms of the stress and displacement distribution and the tension strength of the rock mass, the critical failure vibration velocity of surrounding rocks mass is obtained in different condition.
