Study And Application Of Soil Nail Wall In Deep Foundation Pit

Deformation law and control plan of the environment caused by deep pit excavationis an important subject in the process of urban development. In this paper, the deepfoundation pit support of Jinan for the project engineering background,on the basis ofconducting in-depth analysis in related research results at home and abroad, use themethod of integration of site monitoring, theoretical analysis and numerical simulation.Focus on step-by-step excavation of the deep excavation works in the composite soilnail wall supporting structure of the force and deformation. In the times,This papertakes the topic typical geological environment of Jinan, submountain alluvial plainaccumulativeformation, as the main research background, we adopt the combinationmethod of theoretical analysis and numerical simulation, and take deep research ondeformation law and control plan of the environment considering the deformationfactors, formula deduce, earth surface subsidence law and comparation of simulationvalue, calculation value and measured values, analyze the factors that influencedeformation of the surrounding buildings, clear the influence degree of each factor andrank the factors.The task includes the following items:(1) Summary and analysis of the character and the development of soil nailingtechinique home and abroad, and the constitution, merits and faults of the soil nailingtechnique.(2) Based on specific engineering, study of the design and construction of the soilnailing technique.(4) Analyze the factors that influence deformation of the surrounding buildings,clear the influence degree of each factor and rank the factors(5) Site test and monitor on the soil nailing technique.
