摘要
基于条形和圆形基础下土的极限承载力研究，结合滑动土体绕桩时极限阻滑力的理论解答，导出了复合桩基承台下土的极限承载力由于桩的遮帘作用而获得提高值的理论解，并给出相应的计算图表。算例和实例分析表明了理论解的合理性。此外。
Based on the ultimate bearing capacity of soils under strip and circular foundations and the theoretical solution for the ultimate resistance to the soil sliding around a pile, the theoretical formula of the ultimate bearing capacity increment of soils strengthened by piles under the strip and circular caps of compsite pile foundations are deduced, and the relevant calculating charts are also given. The reasonableness of the formula is shown in some examples and cases. The applicable conditions of the formula is discussed briefly.
