复合地基中桩帽作用数值分析及桩帽承载力计算OA
Numerical Analysis on Action of Pile Cap in Composite Foundation and Calculation on Bearing Capacity of Pile Cap
采用三维快速拉格朗日分析程序，依据某路基试验段的工程地质和设计施工情况建立了路堤荷载下带桩帽刚性桩复合地基数值分析模型，分析了桩帽直径变化对刚性桩复合地基沉降的影响，结果表明：桩帽直径的增大能够起到提高桩荷载分担比、减小复合地基总沉降和桩土沉降差的作用，桩帽直径的变化对下卧层沉降的影响较小。根据相关文献的研究成果，建立了路堤荷载下素混凝土圆板桩帽和倒圆台桩帽的承载力计算方法，并结合实例验证了承载力计算方法可靠性。研究成果可为路堤荷载作用下刚性桩复…查看全部>>
Using three-dimensional Fast Lagrangian Analysis of Continua and depending on the geological, design and construction conditions of some testing sections in certain subgrade engineering, the numerical analysis model for rigid-pile composite foundation with pile cap under embankment load is established and the influence of diameter variation of pile cap on the settlement of rigid-pile composite foundation is analyzed. The result shows that the increased diame…查看全部>>
