滨州至德州高速公路单桩竖向抗压静载试验分析与计算

利用桩基自平衡测试方法的试验结果,结合桩基设计规范,分析了黄泛平原地区桩基承载力的受力特点与影响桩基承载力的主要因素。试验与分析结果表明,黄泛平原地区第四系冲积物以亚砂土、亚粘土夹粉细砂为主,多层结构居多,上层多为粘性土。此种工程地质条件下,影响桩基竖向承载力因素较多,特别是桩基施工质量与桩基混凝土浇筑对桩基竖向承载力影响较大。

The analysis and calculation of solely vertical compression pile test on the Binzhou to Dezhou Highway

Making use of the pile results of self-balancing test and combining with pile design specifications,the paper analysis the mechanical characteristics and main influent factors of pile bearing capacity of the Yellow River plain areas.Test and analysis results show that the Yellow River plain area of Quaternary alluvial deposits of sand,sub-folder fine sand clay-based,multi-layered structure of most of the upper clay mostly.In such engineering geological conditions,the impact of vertical bearing capacity of p...
