Application Of Soil Nailing Supporting Technique In Construction Engineering

soil-nailing supporting is a new method for deep foundation pit supporting. The action mechanism of soil-nailing is extremely complicated . This paper focuses on a discussion of following issues through a combined of theoretical analysis and numerical calculation , and of theory-oriented , engineering analogy , experience and quantitative test . The stability analysis of slopes of deep foundation pit ; checking caculation of tensile breaking limiting condition of soil-nailing , grouting nail sheath anchored limit condition , rising of bottom of foundation pit and piping . Measures are proposed for applying this method to slit stratification in disadvantage geologic .
