〔摘 要〕以某海外工程為例，介紹了該項(xiàng)目地質(zhì)分層情況，以及土壤電阻率和硫酸鹽含量情況，判斷該工程場(chǎng)地具備一定的腐蝕性。基于地勘資料，綜合考慮了預(yù)應(yīng)力管樁、混凝土鉆孔樁及旋挖植樁法等樁型方案，并進(jìn)行了相關(guān)計(jì)算，對(duì)樁基方案進(jìn)行了綜合比選，提出了最優(yōu)樁基方案。

〔關(guān)鍵詞〕旋挖植樁；鉆孔灌注樁；預(yù)應(yīng)力管樁；樁基檢測(cè)；樁基施工

Abstract  Taking an overseas project as an example， this paper introduces the geological stratification， soil resistivity， and sulfate content of the project， and determines that the project site has a certain degree of corrosiveness. Based on geological investigation data， pile structure options such as pre-stressed pipe piles， concrete bored piles， and rotary excavation for piling were fully taken into consideration， and relevant calculations were conducted. The optimal pile foundation scheme was proposed by comprehensive comparison and selection.

Keywords  rotary excavation for piling; bored cast-in-place piles; pre-stressed pipe piles; pile foundation detection; pile foundation construction
