| 摘 要： | 以河南某电厂技改工程为例 ,根据现场检测结果 ,探讨了影响静压预制桩沉桩深度成因 ,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。对于河南某电厂技改工程场地 ,尽管桩端进入砂较小深度 ,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。

| Abstract: | The causes affecting on the installation depth of hydraulically preformed pile and the distribution regularities of bearing capacity, taking one power plant in Henan Province as a case, are studied from in-situ tests results in this paper. The study result indicates that the installation depth of the pile and its bearing capacity are affected by the property of foundation soil. In the case study, though the depth of pile is smaller than that designed, the bearing capacity is enough to meet the need of construction. |
