摘要
由于微型桩的施工工艺与普通灌注桩有着根本的不同，采用普通灌注桩的承载力经验公式估算出的微型桩承载力与其实际值相比偏低，应根据桩周土质条件的不同对其承载力予以适当提高。
The value of result is relatively low if calculating the vertical bearing capacity of micro pile by the empirical formula of normal drilling pile. It dues to the entirely different construction procedures. Coefficients for enhancement should be added to the formula with regard to the soil surrounding the piles.
