According to the field test results of static load experiment of the manual bore cast-in-place pile, the author analyses the mechanism of load transferring and the characteristic of bearing capacity of the pile. The method of static load experiment of the manual bore cast-in-place pile and some interrelated problems in the structural design are discussed. Some suggestions are provided,which may be taken as the reference in the engineering.
Keywords: manual bore cast-in-place pile; static load experiment; frictional resistance; end bearing; settlement
