摘要
灌注桩因其对各种土层的适应性强、桩基承载力高和施工时对附近建筑物及环境影响小等特点,在沿海桩基工程中得到广泛的应用。然而在厚度不均的抛石棱体层中进行冲孔灌注桩施工,在我国工程建设史上还不多见。文章介绍对海上抛石棱体层冲孔灌注桩成孔施工的工程实践经验和施工工艺方面的一些体会,供同行参考。
Cast-in-situ pile has been widely applied in coastal pile foundation engineering due to the strong adaptability to all soil layers, high bearing capacity and small influence on surrounding structures and environment. But, construction of punched cast-in-situ piles in rubble-mound layer of uneven thickness is still rare in China′s engineering history. This paper introduces the experience gained from engineering practice of holing construction for punched cast-in-situ concrete piles in offshore rubble-mound layer and some understandings to construction technology, providing a reference for technicians of the same trade.
