北京地铁5号线桩基静载试验研究

Static Loading Test of Piled Foundation of Beijing Metro Line 5

介绍北京地铁5号线3根试验桩采用自平衡法进行静载试验的情况。通过这次试验得到各试验桩的极限承载力、桩侧摩阻力和桩端阻力等重要参数。由于采用了自平衡法测试,解决了地铁建设中大吨位桩基承载力测试的难题。

This paper presents the static loading test conducted with 3 piles in the manner of self-balance for the Beijing metro line 5. The test was successful in obtaining some important parameters such as limit load of each pile undergone test, friction resistance of the pile side and the resistance at the pile end.
