The Coupling Support Technology for Y Style Large Span Intersection in Deep Soft Rock Roadway

Abstract:

Article Preview

Because of crossing point’s large span, stress concentration clearly, result in parts of the intersection of poor support, construction and maintenance difficult, especially Y-Intersection is more serious part of deformation and failure. Through situ investigation and theoretical research, summarize the typical failure modes of the deep large Y-intersection, analyze the main reasons for destruction of the crossing point that is both sides of Bovine unconstrained and supported respectively. The new coupling supporting design—bolt-mesh-cable + truss to control the top of crossing point , while the key technology of the double control bolt is used to control the Crossing point.—is proposed.
