Study on Vibration Displacement of Ground Building Caused by Construction of Shallowly Bored Tunnel with Drill and Blast Method

Abstract:

A mathematical formula to calculate relative horizontal displacement of ground building due to blast vibration of surrounding rock for bored tunnel by drill and blast method is propounded on the basis of differential equation for dynamic vibration, and the mathematical expression is deduced by means of Laplace transforms. The main factors which influence the horizontal displacement of ground building subject to rock blasting are also discussed in the paper.
