【摘要】 在实际工程中，解决基础抗浮问题常用的抗浮构件有抗浮锚杆和普通抗拔桩，但随着《建筑工程抗浮技术标准》(JGJ 476-2019)的实施，采用压力型抗拔桩解决基础抗浮问题成为抗浮领域的重点研究方向。本文主要介绍了U型管压力型抗拔桩的设计理念、结构组成、施工控制措施以及检测，并通过工程实例与普通抗拔桩进行对比分析，表明U型管压力型抗拔桩具有桩身不产生裂缝、施工效率高、造价低、耐久性好、低碳环保等优点，在各类抗浮工程中具有很好的应用前景。更多还原

【Abstract】 In practical engineering, the anchor against uplift and pile against uplift are often used to solve the anti-floating problems. However, with the implementation of the Technical Standard for Building Engineering against Uplift(JGJ 476-2019), the pressured pile against uplift used to solve the anti-floating problems has become a key research direction in the anti-floating field. The design concept, structure composition, construction control measures and detection of the U-shaped pipe pressured pile against uplift are introduced, and through an engineering example, the U-shaped pipe pressured pile against uplift is compared and analyzed with the conventional pile against uplift. It is concluded that The U-shaped pipe pressured pile against uplift has many advantages: no crack generated in the pile body, high construction efficiency, good durability, low cost and low carbon environmental protection etc. It has a good application prospect in all kinds of anti-floating engineering.更多还原
