[摘要] 通過(guò)對(duì)影響樁基技術(shù)經(jīng)濟(jì)要素的分析，提出了樁基優(yōu)化設(shè)計(jì)的簡(jiǎn)便方法。該方法以單位荷載成本為出發(fā)點(diǎn)，充分考慮了地質(zhì)條件、上部結(jié)構(gòu)形式、承臺(tái)形式、成樁可行性等對(duì)樁基技術(shù)經(jīng)濟(jì)性的影響，對(duì)合理選擇樁基設(shè)計(jì)參數(shù)和樁基設(shè)計(jì)優(yōu)化具有重要的參考價(jià)值。

[關(guān)鍵詞] 樁基；優(yōu)化設(shè)計(jì)；單位荷載成本；樁比表面積；布樁系數(shù)

Abstract: A simple method for optimizing design of pile foundation was proposed. This method based on the cost of the unit load, and took full account of the impact of the economy on the pile foundation in the aspect of the geological conditions, structure form, cap form and pile feasibility etc. It will guide you to select a reasonable pile foundation parameters. This method has an important reference value on pile foundation optinuzing design.

Keywords: pile foundation; optinuzing design; unit load cost; pile specific surface area; piles arranged coefficient
