摘要
龙滩升船机中间渠道在跨越冲沟处须采用渡槽结构。鉴于渡槽结构尺寸较大,承受的荷载较大,使用时须考虑动水作用及结构防漏要求,对渡槽结构形式进行了比选及三维静、动力分析计算,以确定各工况下结构应力、应变状态,为结构体系的局部修改及结构配筋设计提供依据。
In the middle section of the two-stage ship lift in Longtan Hydropower Station , aqueduct structure is adopted to cross the gully .Due to its large dimensions and big load , the dynamic action and leakage proof requirement must be considered.Thus, structure form comparison and three dimensional static and dynamic analysis are carried out to deter-mine the structural stresses and strains , which provide references for the modification of structural design and also the re-inforcement design of the aqueduct .
