摘要:
介绍了某工程中人工挖孔扩底桩的竖向静载荷试验情况,揭示了其承载力严重不足的原因。试验结果表明,扩底桩的承载力不仅与桩端尺寸有关,而且还与桩端土的状态有关,土质越软,极限承载力越小。因此,在较软弱的地基上,不宜采用扩大桩端尺寸的办法来提高承载力。
Abstract:
The experimental situation of the vertical static load of the artificial digging piles in a certain project was introduced, and the cause of its serious lack of bearing capacity was revealed. The test results show that the bearing capacity of the expansion of the bottom pile is not only related to the size of the pile end, but also related to the state of the pile ends. The soft the soil, the smaller the limit bearing capacity. Therefore, in the weaker foundation, it is not advisable to use the size of the pile end to increase the bearing capacity.
