| 摘 要： | 以十堰至天水高速公路段仙鸡河大桥采用桩端后压浆技术的钻孔灌注桩为研究对象,通过理论分析和非线性有限元程序ADINA仿真分析,对采用桩端后压浆技术后的钻孔灌注桩的承载性能进行了研究,得出结论：采用桩端后压浆技术形成桩端注浆加固层,提高桩端土变形模量,可以有效地减小桩基在正常使用状态下的沉降量,在水泥用量极小的情况下就可大大提高灌注桩的极限承载力,其极限承载力比未压浆的提高约69%,可为相关领域的工程提供一定的借鉴。

| Abstract: | Taking the bored pile treated by post-grouting technology of Xianji River Bridge on Shiyan-Tianshui Expressway as research object,through theoretical analysis and simulation analysis with nonlinear finite element program ADINA,the load-bearing characteristic of bored pile treated by post-grouting technology is studied.The conclusions are: using post-grouting technology to form reinforcement layer of pile injection can heighten the deformation modulus of pile-end soil,effectively reduce the settlement of pil... |
