摘要：

今后,国内外均有大量的建筑物达到甚至超过其设计使用年限,拆除后重建的工程项目将呈上升趋势,而国内外对此类问题尚无较详细的报道。通过巴基斯坦卡拉奇港OP- 旧高桩码头322根群桩基础的拔除施工,探索并总结出了一种成本费用较低、拔桩效率高的水上拔桩方法。

From now onwards,there will soon be a lot of structures that come up to or even exceed their designed service life both at home and abroad.Rebuilding works after demolition of old structures will be on the increase and there hasn't been detailed reports on these works so far at home or abroad.In this paper,methods for extraction of piles on the water with low cost and high efficiency are explored and summarized on the basis of the experience in the works for extracting 322 piles in the group-pile foundation for the old OP-Ⅱ piled jetty in Karachi Port,Pakistan.
