Anchor Piles Composite Soil Nailing Support Technique In Applied Research In The Loess Excavation

With economic development and urban construction dramatically increasing,complicated geological situation and surrounding environment influence more and moreconstruction, combined with the transformation that new buildings have been given tothe senior and super senior trend,pitting deeper and deeper, the traditional pit alreadycannot meet the needs of the current development. Composite soil-nailed retaining wallis dominated by soil nailing, assisting other reinforced measures to maintain andenhance soil stability of compound support form. It is traditional support in the form ofsupporting structure load effect of disturbance of soil into a part of the support structure,which can effectively use the Foundation pit support under special environment, andhave a simple process, low cost, short duration and so on. But composite soil nail walltechnology both in the theoretical analysis method and in engineering practice is notmature enough and perfect.Taking XI’an DaXia International Centre for great summer projects forexample,The paper provides an overview of features, deformation of deep Foundationpit supporting mechanism and effect factors,and it is currently widely used inFoundation pit support of soil-nail retaining wall and destructive manner provides asummary and analysis,which combined with geological conditions and the surroundingenvironment of the project area.Based on relevant theories and methods described inthis article, an analysis of Foundation pit project of summer International Center andcomposite soil-nailed wall of deep Foundation pit supporting scheme of constructionelements are studied,and application of value engineering theory analysis anddemonstration of the construction programme are used to select the best program. Through this study on the composite soil-nailing wall support, the application ofdeep Foundation pit support engineering is deeped, and the use of value engineeringtheory to the analysis of composite soil-nailing wall technology provides a way ofoptimization, which can provide reference for similar projects.
