Influence of Blasting Vibration on Adjacent Circular Chamber with Lining

摘要：

The wave function expansion method is used to analyze the interaction process of the blasting seismic wave and the adjacent underground circular chamber with concrete lining, the stress expression, displacement expression and vibration velocity expression of underground circular cavity under the acting of blasting vibration are deduced, the stress and displacement distribution of surrounding rock mass and concrete lining are presented under the definite condition. In terms of the stress and vibration velocity distribution and the tensile strength of the concrete lining, the critical failure vibration velocity of concrete lining is obtained.
