摘要: 基于目前国内外文献对加筋地基承载力的研究成果,总结了加筋地基承载力的影响因素及其影响规律,并基于已有文献的研究成果得到了最优加筋参数的建议取值范围。对目前加筋地基的破坏模式及承载力计算公式进行了总结,并讨论了各承载力计算公式的区别与联系及优劣性。提出加筋地基承载力计算公式应基于准确的破坏模式与加筋机理。加筋地基的破坏模式与破坏模式类型定量化判断标准、加筋机理、原型实验等应成为加筋地基承载力未来的研究重点。Abstract: This paper summarized the influence factors of bearing capacity of reinforced foundation on the basis of the historical literatures, and proposed the optimum parameters of reinforced foundation. The paper also summarized the failure modes of reinforced foundation and analytical solutions, discussed advantages and disadvantages of formulas used to calculate bearing capacity of reinforced foundation. It is advised that calculation method of bearing capacity of reinforced foundation should be based on accurate failure mode and complete reinforcement mechanism. And research on failure modes and quantified standards to identify the type of failure modes, reinforcement mechanism, and large scale tests should be the focus of research in future.
