摘要
回顾分析了近年来500 kV及以上等级的送电线路中灌注桩基础的一些研究成果和发展趋势。介绍了板式中型桩、空心桩、斜桩、带翼板的桩、微型树根桩等几种新的桩基础形式,从上拔、下压稳定性及配筋计算等方面分析了各种桩基础的优点及适用条件,对混凝土消耗量及经济性也进行了一些分析。
A number of research and development trends of pile foundation in the transmission line of 500KY and above grades in recent years are reviewed and analyzed. Several new forms of pile foundation are introduced, such as medium-sized piles, hollow piles, inclined pile, pile with a wing, icro-root piles. From uplift,pressure stability and reinforcement calculation,the advantages and application conditions of several pile foundations, and concrete consumption and other economic indicators are analyzed.
