摘　　要：介绍了桩承载力自平衡测试技术近 5年来在国内桥梁桩基检测中的应用情况 ,包括润扬长江大桥、苏通长江大桥、杭州湾跨海大桥、南京长江三桥等国家重点工程。被检桩最大桩径为 2 .8m ,最大桩长 12 5 m,最大承载力达12 0 0 0 t。检测结果直接用于工程实际中 ,充分发挥了大直径超长桩基的承载潜能 。The engineering applications of self-balanced test technique are summarized in internal bridge piles, including Runyang Yangtze River Bridge, Sutong Yangtze River Bridge, Hangzhou Bay Sea bridge and Nanjing No.3 Yangtze River Bridge which are national key engineering. The tested piles are up to 2.8 m in diameter, 125 m in length, 12 000 ton in bearing capacity. The test results are applied in engineering design, which brings bearing capacity potential of superlong piles into play and achieves remarkable economic benefits.
