引入可靠度理论进行桶形基础的评价 ,将土壤的抗剪强度指标 c、φ和物理性指标γ以及海冰的厚度 h、单轴抗压强度σc视为随机变量 ,计算统计量并分析得出各自的概率分布。针对桶形基础的不同失效模式建立承载能力极限状态下的极限状态函数。用计算机程序计算分析了一桶形基础实例的可靠性。 The reliability theory is introduced to evaluate the bucket foundation. The shear strength index c, φ and the physical index γ of the soil as well as the sea ice thickness h and the uniaxial compressive strength σc are regarded as random variables, and the statistics are calculated and analyzed The respective probability distribution. For the different failure modes of bucket foundation, the limit state function under the limit state of bearing capacity is established. The reliability of one barrel basic example was analyzed by computer program.
