钻孔灌注桩以其承载力大、沉降量小、稳定性好、桩径和桩长可变等特点在高层建筑基础工程中得到广泛的应用。但由于受施工工艺的限制,成桩过程隐蔽,影响钻孔灌注桩承载力的因素较多,要提高钻孔灌注桩承载力应注意以下几点 Bored piles are widely used in the foundation engineering of high-rise buildings because of their large bearing capacity, small settlement, good stability, variable pile diameter and pile length. However, due to the limitation of construction technology, there are many factors that affect the bearing capacity of cast-in-place bored piles because of the concealed pile forming process. The following points should be paid attention to to improve the bearing capacity of bored cast-in-place piles
