摘要
依据钻孔灌注桩后注浆机理,采用合理的假设,建立了钻孔灌注桩后注浆工艺参数估算模型,并采用模型结合国家体育场基桩工程,计算了其主要后注浆工艺参数,与该工程实际采用的参数进行了对比,结果表明注浆量模型和注浆压力模型在实际的后注浆工程项目中具有很好的指导意义。
Based on post grouting mechanism of bored pile, applying rational hypothesis, the calculation model of post grouting technology parameter of bored pile is established. Combining with national stadium foundation pile engineering, the essay calculates main post grouting technology parameter, and compares it to aetual parameter. Results show that grouting model and grouting pressure model has good guiding meaning in post grouting engineering project.
