Retaining Structure And Stability Research Of Civil Defence Fortihcations Of Liberation Avenue

With the rapid development of social and economical, urban population isincreased rapidly, and the development of urban construction is also increased rapidly,therefore, high-rise buildings are more and more, leading to the pit is getting deeper andthe area greater. For the excavation which is complex subject, how to find a retainingscheme of actual project, optimization is very important to the excavation of theretaining structure. Safety is a primary consideration to excavation, so warning researchof deformation to the optimal retaining scheme that is economic and technical has moreimportant practical significance.For civil defence fortifications the liberation avenue, using the analytic hierarchyand gray system theory to economic comparison and comprehensive evaluation of itsretaining scheme.verifying that the project selected the retaining scheme of soil nailwall is reasonable. And use the numerical simulation software simulating soildeformation of the soil nail wall retaining, and analyze the monitoring deformation.According to the simulation and analysis, comparing the simulating value andmonitoring value of the displacement with early warning, and confirm the truth of theproject use the soil nail wall retaining is safe and reasonable.
