建立了岩石高边坡分步开挖稳定性反馈分析模型,分析过程中考虑了岩体爆破松动及卸荷的影响.对三峡工程永久船闸高边坡各开挖步进行了相应的预报,结果表明,该方法具有较高的实用价值
The stability feedback analysis model of high-slope side rock excavation was set up and the influence of loosening and unloading of rock mass was taken into account in the analysis.The corresponding prediction was made for each excavation step in the high slope of Permanent Ship Lock of the Three Gorges Project. It shows that this method has high practical value
