Fluctuations of the ground surface at blasting operations on tunnel structures

The paper considers the fluctuations of ground surface during blasting operations on tunnel structures. To estimate vibration levels soil surface, under explosive action inside a cylindrical cavity, we will consider plane problem elasticity theory as first approximation. main purpose work is to determine stress-strain state pipelines influence seismic waves. As result this impact, longitudinal and transverse waves propagate in ground. solve problem, reciprocity theorem applied, for dynamic problems results obtained are compared by wave dynamics methods. solution makes it possible that occur impacts cavity elastic half-space. can be used assess structures shallow tunnels laid drilling blasting.
