对山东省陡山水库放水洞衬管进行了纵向配筋的校核计算。计算和分析表明:原设计对衬管未做纵向结构分析,而只按最小配筋率进行构造配筋,是该水库衬管产生环向裂缝的最主要原因。
The calculation of longitudinal reinforcement of lining pipe of Doushan Reservoir in Shandong Province was carried out. The calculation and analysis show that the original design did not make the longitudinal structural analysis of the liner, but only the minimum reinforcement ratio to construct the reinforcement, which is the main reason for the circumferential cracks in the liner.
