摘要
总结了渡槽结构分析方面的新进展,认为全面评价渡槽结构的静、动力特性应综合考虑槽内水体与槽壁的动力相互作用,桩、土和桩与结构的动力相互作用问题。提出了合理确定地震动参数的途径。以南水北调中线穿黄U形渡槽为例,进行分析研究,得出了可供工程单位参考应用的有益结论:渡槽槽身的静动位移和应力均在允许范围内,渡槽地基系统的主要受力部位在桩顶部,桩顶部为控制断面,应合理配筋。
A review of recent development in analysis method for structure of aqueduct is presented.It is pointed out that the dynamic interactions between water and aqueduct wall,between piles and soil as well as between piles and aqueduct structure must be carefully considered,in order to comprehensively assess the static and dynamic characteristics of the aqueduct.The approach to determine the seismic parameters in dynamic analysis is proposed.The large-scale U-type aqueduct in South to Middle Route of North Water Transfer Project is used as an example for demonstration.
