| Abstract: | In the tunnel construction by drill-blast method, excessive or insufficient excavation is ineluctable. It has not only important influence on the work quality and the safe progress in the tunnel construction, but also on the economic benefit in tunnel engineering. This article based on the engineering practice, analyzes five main factors affecting the excessive or insufficient excavation:drill precision, the act of measuring, blasting technology, the geology of wall rock and real - time management, and the relevant technology of its control is put forward. |
