| Abstract:The smallest diameter limit for bored grouting pile construction in Shanghai area is analyzed theoretically and discussed. By a construction case of a bore grouting pile with the diameter of 400 mm, the discussion is made on the measures of construction technologies and quality assurance for the bore grouting pile with the diameter less than 550 mm, and the possibility of the design and construction for bore grouting pile with even smaller diameter is also explored. |
