Abstract

Abstract: Abstract：Based on the grouting micro-pile group combined with support in the calculation of the stability of perilous rock， the number of micro-pile group and the body size of supporting are ensured．To examine the reliability of the scheme froMa macro-perspective，the displacement of the end of the pile should be calibrated．Finally，it is showed in the case study that the grouting micro-pile group and the suppo~joint micro-control technology in the management of the perilous rock are feasi- ble．

Key words: words：perilous rock, grouting micro-pile, support, stability calculation
