The Tunnel Blasting Technology in Karst Structure Beneath Rivers
Based on the practice of China southwest oil pipe tunnel blasting cutting under river in the karat structure, procedures for the program are supposed as: advanced exploring, pre-grouting, rock blasting, ventilation and dust suppression, spoil disposal, supporting and lining in order. It is emphasized that the special blasting plans should be taken according to different geological structures. The blasting plans and blasting-vibration reducing plans, which are used in the reconsoUdated cracked rock by the pre-grouting and the rock with karst features, are introduced. The measures used in the related stages of the under-river-tunnel construction in the karst geological environment are given.
