Tunnels in the Himalayas

18 Jul 2023

Major tunneling problems in India are encountered in the young Himalayan regions, particularly the lesser or lower Himalayas, where the geology is difficult, the rock masses are weak and undergoing intense tectonic activities resulting in major faults, folds and other discontinuities. Compared to this, in the peninsular (Southern part) India where the rocks are strong and less disturbed, tunneling problems are rarely encountered.
