Research on Failure Mechanism and Long-term Stable Operation of rock-bolted crane girder under Complex Geological Conditions
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.
