## 上海电力盾构隧道大-延区间数字化仿真与应用

Digital simulation and application of  Da -Yan  interval of Shanghai electric power shield tunnel
Abstract: Digital shield tunnel is a branch of digital underground space and engineering. It is the shield-tunnel-oriented digitalization.The objective of digitizing shield tunnels is to visualize the complicated underground world, manage the whole life-cycle data of engineering projects dynamically, and facilitate engineering analysis and decision-support, so as to lead to a more efficient use of engineering information, data management capabilities, three-dimensional visualization capabilities and data analysis capabilities.Then based on the idea of decomposing the geometrical objects of shield tunnels, data taxonomy and data model of digitized shield tunnel are presented. Geometrical modeling of shield tunnels and surrounding ground is discussed. At last, three dimensional simulation analysis is carried out, and the stress of the tunnel after excavation is analyzed.
KeyWords: Shield tunnel; Digitizing; Three-dimensional Geometric modeling; Mechanical analysis of lining structure
