摘要
Abstract
The underground caverns of Yebatan Hydropower Station are under joint adverse effect of extremely high stress and complex structural planes.In response to failure phenomenon of rock-bolted crane girder dur-ing the excavation,based on actual failure phenomena on site,microseismic monitoring data,geophysical de-tection and other results,failure mechanism of rock-bolted crane girder is analyzed in depth,and targeted dy-namic optimization design measures are proposed,simulation analysis software is used to calculate the opera-tional safety of the bridge crane under load.The results show that the addition of reinforced concrete buttress walls can meet the long-term safe operation of rock-bolted crane girder.关键词
