某工程项目场地较大,两次试桩的位置不同,PHC管桩承载力差别很大。我公司作为建设单位该项目的技术顾问,对该工程PHC管桩承载力差异大的原因进行了研究分析。通过对该工程场地岩土情况分析,并对不同岩土情况下的单桩承载力进行理论计算分析,阐述该工程PHC管桩承载力差异大的原因,总结PHC管桩承载力与岩土地质情况的对应关系,提出处理措施,为今后类似地基基础设计和施工提供借鉴。 A project site larger, two different locations of test piles, PHC piles bearing capacity varies widely. My company as a construction unit of the project technical consultant, the project PHC pile bearing capacity differences between the reasons for a study and analysis. Through the analysis of the geotechnical conditions of the project site and theoretical calculation and analysis of the bearing capacity of the single pile under different geotechnical conditions, the reasons for the large difference in bearing capacity of the PHC pipe pile are elaborated. The bearing capacity of the PHC pipe pile and the geotechnical geological The corresponding relationship between the situation, put forward the handling measures for the future similar foundation design and construction to provide reference.
