摘要
通过对注浆微型桩群联合支撑技术在危岩治理中的稳定性计算,确定微型桩群的布置数量和支撑体几面尺寸;利用对桩端位移的校核,从宏观角度验证本治理方案的可靠性;最后通过工程实例,验证注浆微型桩群与支撑联合防治技术在危岩治理中的实用性。
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 from a 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 support joint micro-control technology in the management of the perilous rock are feasible.
