岩土参数相关性的地基承载力模糊可靠性分析
摘要:地基的失效可视为模糊事件。影响地基承载力因素表现出空间变异性。根据随机场理论描述土性参数的空间变异性,考虑土性参数的自相关性及其互相关性,得出参数间的相关性在可靠性分析中不可忽视的结论。
Abstract:The fail of foundation is an ambiguous event. The factors, which affect on foundation bearing capacity, appear in spatial variability. The spatial variability of soil is describde by means of the theory of randcan field. Considering the oorreiations of itself and mutuality, it is found that the tcorrelations of soil parameters be important factors to the reliability of foudation bearing capacity.
