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。
Because the construction process of micro piles is fundamentally different from ordinary cast-in-place piles, the micropile bearing capacity estimated from the empirical formula of bearing capacity of ordinary cast-in-place piles is low compared to its actual value. It should be carried out according to different soil conditions around the pile. Strengthen it properly.
