后注浆灌注桩作为一种桩基规范推荐采用的新型桩基础型式,在民用建筑领域应用广泛。由于缺少理论支持和实践应用,尚未在输电线路工程中直接应用。对输电线路领域中后注浆灌注桩的增强机理、设计计算、注浆布置、工艺流程、施工设备、人工材料等进行了实验研究,提出在上拔荷载和水平力荷载作用下后注浆灌注桩的计算方法,并对后注浆灌注桩的主要优点、适用范围、经济性等进行了分析与比较。 Post-grouting pile as a new type of pile foundation recommended for the pile foundation type, widely used in the field of civil construction. Due to the lack of theoretical support and practical application, it has not been applied directly in transmission line engineering. The experimental research on reinforcement mechanism, design and calculation, grouting layout, process flow, construction equipment and artificial materials of post-grouting piles in the field of transmission lines was put forward. After grouting and perfusion Pile calculation method, and the main advantages of post grouting piles, the scope of application, economic analysis and comparison.
