The Study Of Control Technique For Great Deformation Tunnels In Soft Surrounding Rock Of Press

The original is the target with the soft surrounding rock tunnel of press, Research the geology feature that the soft surrounding rock tunnel of press great deformation, Deformation mechanism, Deformation size hierarchical criterion , Excavate to reach the control a sheltering step. Being living to expound on this base this type of tunnel great deformation the application that the control technique is living in the actual projectly.The dissertation was introduced the soft surrounding rock tunnel of press and great deformation that the control technique development reaches such and researcies the present situation, Talking about the press surrounding rock for the main feature and the conditional sum that great deformation happens, Hierarchical criterion that mechanism on the basis of great deformation is analysed and the deformation, Expound the calculation the leading means that the press surrounding rock tunnel of great deformation. Excavating means that is applicable and the step sheltering were summarized, The technique are measured to fathom in the particular step sheltering along with building supervision stressly to expound the press surrounding rock tunnel, Moreover in accordance the initiative renovation rule surrounding rock being aimed at distinctly degree press great deformation that tunnel design and the building proposes the proposal .Finally , Expounding the press surrounding rock tunnel great deformation the application that the control technique is living in twin string tunnel of Xin Wangjiatan of Baolan.Analyse and researcies by means of theory , This dissertation is think to press that the surrounding rock great deformation that tunnel control ought to be establish is living to surrounding rock nature accurately leading to forecast on the base,The relevant step sheltering and the building scheme is takeed before happenning in th-e great deformation being living, The measuring strengthened moreoverin the building supervision survey and fathoming the data and gathering to amounts Analysis,They are the significant measure that successfully builded in the tunnel. Adopt anchor, Notes, Spouting integration that one another the unites surrounding rock consolidates a sheltering technique, Starching to develop the anchor staff to act as core synthesis the repaiing step especially with the notes is living to become deformed greatly that the tunnel shelters,The control respect is highly effective. Being applicable to the press surrounding rock tunnel of great deformation an excavating means and the step sheltering grows more, Ought to fix on the basis of geology conditional sum building technique level of construction site and so on synthesis. Being living, twin string tunnels of fresh Wangjiatan of the Baolan Zengjian two strings projects environment gets off, Practice proof,Strengthening geology leades the forecast, The survey is measured in the supervision, Adopt the self-drive style to explain with notes the thick liquid to develop the anchor staff awaiting a tall crustal stress of the step sheltering renovation, Water pour,The success was acquireed in the great deformation of soft surrounding rock.
