【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成因 ,分析了静压桩承载力的分布规律 .得出静压桩的沉桩深度和承载力与地基土的性状密切相关 .尽管桩端进入砂层深度较小 ,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更多还原

【Abstract】 The causes affecting the depth of jack up pile and the law of distribution of bearing capacity, taking Kaifeng Power Plant , Henan Province as study case, are studied based on in situ tests. The results indicate that pile depth and their bearing capacity are affected by the property of foundation soil. In the case study, though the depth of pile is smaller than that of design, the bearing capacity is enough to satisfy the need of construction.更多还原
