Stress-strain field for explosions with detonating cord in tunneling
Keywords:
Stress-strain field, explosion in tunnels, detonating cord, explosion designAbstract
In this article it is determines the stress-strain field produced in the rock massif of Buenaventura– Sabanilla tunnel after the explosion of the load detonating cord of 40 g/m. The calculation was carried out for a distribution with annular air space between the explosive substance and the load chamber, using the principle of the physical essence for the action of the explosion on the medium. The results were obtained studying the cracks produced in the front of the excavation, and determining the physical-mechanical properties of the rocks. With these values the trituration, cracking and decrustation radii were determined as initial parameters for the explosion design in tunneling.Downloads
