| 中文摘要: |
| 以开封火电厂技改工程为例，根据现场检测结果，探讨了影响静压预制桩沉桩深度原因，分析了静压桩承载力的分布规律。研究结果证明静压桩的沉桩深度和承载力与地基土的性状密切相关。对于开封火电厂技改工程场地，尽管极端进入砂层较小深度，却可以在桩端平面附近良好土层的作用下提供较大的端阻力。 |
| 英文摘要: |
| The causes affecting on the depth of jack-up pile and the law of distribution of bearing capacity, taking the Kaifeng Power Plant of He'nan Province as a studying case, are studied based on in-situ tests. The results indicate that pile depth and bearing capacity are affected by the property of foundation soil. In the case study, though the depth of pile is less than that of design, the bearing capacity is enough to satisfy the need of construction. |
