摘要
顺应大跨径桥梁和高层建筑等结构物下超长桩研究的需要,在现有规范的基础上,给出了超长桩适宜钻芯的最大桩长计算公式,例举了如何制定实体超长桩钻芯的较高要求,分析了配套的钻探技术要点,介绍了桩长74.02m的钻芯实例。
To cater for the need of studying super long piles used for longspan bridges and highrise buildings, this paper works out the formula for calculating the maximum length of the super long pile suitable for core drilling on the basis of the current codes and specifications, illustrates the strict requirements for how to drill cores of the actual super long piles and analyzes the technical essentials of the corresponding drilling techniques. Finally, a case study of a 74.02m long pile is presented.
