Abstract
This paper takes a high-rise building as an example to analyze the project foundation pit protection design scheme.By analyzing the cost of two design schemes of rail row pile support and soil nailing shotcrete anchor support,the optimal scheme is determined.The analysis shows that the unit area cost of the rail row pile support scheme is 1 406.6 yuan/m2,and the unit area cost of the soil nailing shotcrete anchor support scheme is 220.65 yuan/m2.To sum up,the unit area cost of the soil nailing shotgrouting anchor support scheme is significantly lower than that of the rail row pile support scheme,reflecting higher economy and feasibility,and it is determined as the protection design scheme of the deep foundation pit slope of the project.关键词
