Construction of undeground works and tunnels in ancient Egypt

摘要

The Ancient Egyptian has an important role in developing the use of the underground especially in the construction of: tombs, warehouses, water passages, and tunnels which were used as accesses to tombs, worshipping rooms and the warehouses. These tunnels were constructed through rock cutting. The underground construction by the ancient Egyptians was based upon engineering principles represented by the construction angle treatment of the different levels, the required height declination angles and the construction method itself, either by rock digging or stone construction.
