Analysis construction method of double-decked electric power tunnel

With the development of modern technology and space, more and more cities begin exploit underground space, to satisfy the increasingly crowded environment. This article base on double-decked electric power tunnel of 220KV 1 cut change project, use the finite element software MIDAS/GTS analysis and simulation the project construction process of two different method, through all the simulation of construction process, and analysis the engineering the feasibility construction method.lt is the first time use the double-decked tunnel construction methods in Beijing, to discuss and analysis the method of the project have an important significance, in the meanwhile, it can provide some references to similar project construction.
