摘要
从试验入手分析了粉土中后注浆灌注桩的承载力机理,分析了不同注浆范围和注浆量对承载力的影响。根据注浆的分布效果,建立了后注浆桩的数值模拟模型,并用于实践,计算结果表明,注浆对计算有较大影响。
Base on model test, principle of bearing capacity of post grouting pile in silt are discussed. The influence of grouting range and volume are analyzed on bearing capacity of pile . The numerical simulation models are proposed based upon analysis of effect of grouting. The calculation results manifests that influence of grouting can ＇t neglected for estimation of bearing capacity of post grouting pile.
