Abstract:CFG pile composite foundation is applied in a project according to its special demand and characteristic geological condition. The problems that might be met in construction are analyzed and the corresponding detail measures are presented. The results of plate loading test and low strain dynamic testing show that the quality of CFG pile composite foundation is good and subgrade bearing capacity has been improved successfully.
Keywords:CFG pile composite foundation; vibrating tubular; plate loading test; low strain dynamic testing
