This work improves the so-called displacement- based method and addresses the very real need of assessing the safety of lattice girder shotcrete support during tunnel construction.
实例分析表明，所提方法的评价结果能够正确反映隧道的实际安全状态，得到的可靠指标也与我国规范所要求的范围相一致。
Based on the previous research, lattice girder reinforced shotcrete support is dealt with, and a method is set up to evaluate the safety of this kind of support for a tunnel in construction.
在过去研究成果基础上，建立施工期隧道格栅钢架喷混凝土支护的安全性评价方法。
