| Abstract: | Research purposes:This paper based on the engineering example of large section loess tunnel of Zhengzhou-Xi'an passenger dedicated line,focuses on distortion features of the sandy loess and the different constructions methods of large section loess tunnel,illustrates the method for how to choose the reasonable measuring project,measuring frequency and measuring methods,analyzes the measuring data to master the deformation regulation of the large section loess tunnel. Research results:Combining the construction practice of Qindong tunnel project large section loess tunnel, this paper gets the change regulation of the large section loess tunnel such as vault' sinking,level convergence, steel frame strained,surrounding rock stress and shaft force which have the favorable guiding significance. |
