摘　　要：依据加筋地基理论和现有试验的结果,提出设置加筋垫层条形基础的地基破坏模式,运用极限分析的上限原理推导设置加筋垫层条形基础的地基极限承载力的上限解.结合工程实例,得出与目前已有计算方法基本一致的计算结果,验证了该上限解的合理性.Based on the theory and test results of reinforced foundation,an upper bound failure mode is proposed. The limit analysis method is used to deduce the bearing capacity of reinforced foundation. It is shown that the calculated upper bound solution of the ultimate bearing capacity is in reasonable and agreement with the results of other methods.
