【摘要】 涵洞式渡槽是南水北调中线输水工程河渠交叉建筑物的主要形式之一,目前国际流行的可靠度分析方法在渡槽上运用不多,针对涵洞式渡槽的主要结构的失效模式进行了分析,建立了相应的功能函数,并得出了相应的可靠性指标,在考虑各结构相互性的基础上,计算了涵洞式渡槽结构的系统可靠度。更多还原

【Abstract】 Culvert aqueduct is the main form of river-graff-cross building in Mid-route of South-to-North Water Transfer Project,and reliability analyse mothod was seldom seen used on aqueduct structure.The failure mode of the primary structures of culvert aqueduct is analyzed and the corresponding reliability indices is achieved.Based on the interdependent effect of each structure,system reliability of culvert aqueduct structures is calculated.更多还原
