【摘要】 三峡水利枢纽在汛期调洪和船闸充、泄水运行全过程,在上、下游引航道内将产生不同程度的非恒定流,对航运构成相应的不利影响。本文结合坝区河势特点及上下游引航道布置,试验研究了大坝泄洪及船闸充泄水非恒定流对上、下引航道通航影响,同时进行了非恒定流通航条件评价及改善措施研究。更多还原

【Abstract】 In the whole course of flood regulation of TGP during flood season as well as filling and discharging of its shiplock,unsteady flow at different levels will occur in the upper and the lower access channels,which will exert an adverse impact on the navigation.Based on the river regime of TGP dam area and the arrangement of upper and lower access channels,the experimental research on the influence of such unsteady flow on the navigation,the evaluation of navigable conditions under the unsteady flow and the study of corresponding improvement measures are presented in this paper.更多还原
