摘要
依据工程岩体的力学介质分类,利用块体理论与赤平投影方法,建立了块裂力学介质工程岩体中块状岩体的稳定可靠性分析模型。并利用该模型分析了某大型地下空间块状岩体的稳定概率。所述工程实例展示了模型的实用性和应用前景。
Based on mechanics classification of media,a reliability model for blocky engineering rockmass stability is made by mean of block theory and hemispheric projection. The stability probability of blocky surround rocks in a large underground opening is calculated according to the reliability model. The applying prospects and adaptation of the model are shown by project example.
