Abstract Research purposes: The researches are done on matching rapid construction technology with machinery for highland stressed weak wall rock tunnel for the purposes of setting performance of large-sized machinery in construction of highland stressed weak wall rock tunnel and providing mature and high efficient mode of matching construction machinery with construction technology.
Research conclusions: For rapid construction of the tunnel under condition of highland stressed weak wall rock, first, there should be a support with enough strength to resist the deformation of wall rock and the wall rock should be closed on time with suitable method to form a closed support ring to set performance of the support; then the construction machinery is matched according to the construction method and conditions.
