摘　　要：结合某地下工程施工软岩实际情况,为验证钢格栅喷混凝土初期支护设计强度的合理性,采用专业岩土分析软件FLAC-3D建立相应的数值模型,对支护设计参数的围岩控制效果进行了分析,并与现场实际观测效果进行了比较,证明了支护措施的科学有效性。Combined with the situations of soft rocks in one underground engineering, in order to test the design strength of primary support method of shotcrete on steel grill corresponding numerical calculation model is built utilizing professional software of geotechnical engineering. Based upon this model control effects of surrounding rock under those support design parameters are analyzed. Comparison is also made between measured effects, which verified the validity of this support method.
