摘要

A new construction method by laser excavation is studied. First, the fundamental experiments were conducted for investigating the interaction between rocks and laser.s Next, some parts of lasers were improved. Two beams generated by the YAG laser system are coupled to gain the 6kw beam. This is applied through a long focus lens on the rock excavated from the similar place in which the large- scale rock failure occurred. 10-minute irradiation produced a small hole of 230mm depth and 20mm in diameter. The same experiment is achieved out of doors to demonstrate laser boring has a practical use.
