[提要] 考察了廣東地區(qū)預(yù)應(yīng)力高混凝土管樁（PHC樁）在工程實(shí)踐中存在的問題，對不同的地質(zhì)狀況下制定打樁收錘標(biāo)準(zhǔn)、樁約束設(shè)計(jì)、承載力計(jì)算、估算樁長等爭議問題進(jìn)行了論證，提出了修正技術(shù)方案。
[關(guān)鍵詞] 預(yù)應(yīng)力高強(qiáng)混凝土管樁 復(fù)雜地質(zhì) 收錘標(biāo)準(zhǔn) 成樁質(zhì)量 約束設(shè)計(jì)Based on fieldwork investigations,questions of PHC-pile foundation in Guangdong province are talked about. Views and suggestions are presented to identify different complicated foundation soils,and the condition for stopping hammering, the design for confinement, the calculation of bearing capacity, the estimation of pile length are presented.
Keywords: PHC pile; complicated foundation soils; stop hammering condition; pile quality; confinement design參 考 文 獻(xiàn)
