Tunnel Excavation and the Use of System Anchor Rod

this tunnel construction was based on the Shinoku law I,in close combination with the realities of design and construction,different adjacent formation excavation methods were chosen.The design concept was well realized in the construction,different construction plans were adopted different excavation were carried out.The construction plan was well realized and experimental contrast between two anchors way was done.The overall construction achieves the expectation effect,the construction time is also under ...
