论大直径灌注桩的设计、施工

Discussion of design and construction for full diameter cast-in-place concrete pile

大直径灌注桩广泛用于房屋、桥梁的基础工程中,当无水、少水且持力层为岩石、卵石层等理想土层,埋置深度在20m左右,采用大直径灌注桩为基础,能取得质量可靠、造价经济的优良桩基。介绍了有关设计、施工的基本知识,对桩基设计、施工具有一定参考价值。

The full diameter cast-in-place concrete pile is widely used in construction of foundation forbuilding and bridge.Using full diameter borehole cast-in-place concrete pile can obtain better pile foundation when the soil lacks of water and supported by rock and cobble, the depth about 20m. This paper introduces the points for attention about design and construction.
