大直径沉管灌注桩在龙景大厦工程中的应用

THE APPLICATION OF FILLING PILES WITH LARGE DIAMETER SINK-PIPE IN THE LONGJING BUILDING

介绍了大直径沉管灌注桩在深圳市龙景大厦施工中的具体应用 .针对工程地质性能指标 ,对各种桩基方案进行对比 ,论证了该项工程使用Φ 65 0 mm沉管灌注桩的可行性 .实际施工表明 ,该工程采用这种技术效果良好 ,单桩承载力均大于 1 60 0 k N。

The practical application of filling piles with large diameter sink-pipe in the Longjing Building is introduced. According to the geological properties, the feasibility of filling piles with large diameter sink-pipe (Φ650mm) is justified after a number of schemes have been compared with each other. The practical construction shows that the effect of this technology is very well and the bear ability of each pile is higher than 1600KN, which meets the designed need.
