摘要
结合各种地基土的原始载荷板试验资料,用太沙基理论公式、汉森理论公式和魏西克理论公式进行了钱基础极限承载力的计算,对计算模式的不确定性、土性固有的变异性及由其引起的极限承载力的不确定性等进行了研究;根据以上计算结果,计算了各类地基土承载力的可靠度指标;结合上部结构的荷载标准及分项系数,计算了各类地基土承载力的分项系数。
Based on the plate-bearing test on various foundation soils, the ultimate bearing capacities of shallow foundations are calculated from Terzaghi's theory, Hnasen's theory, and Vesic's theory. The uncertainties related to the methods of analysis, soil properties, and the calculated ultimate bearing capacities Puj are analyzed in this paper. In the light of the above results, the reliability indexes βof bear- ing capacities of different sub-soils are obtained. The.partial coefficiens of the bearing capacity of various sub-soils are calculated in com- bination with the loading standard and the partial coefficient of the upper structure.
