摘　　要：介绍了南流江预应力连续梁式渡槽工程中渡槽支座的比选、设计和验算。首先,基于工程实际条件,结合三种不同支座方案的优缺点进行了分析,确定了最优支座方案;随后,采用Midas-civil和桥梁博士两种分析软件建立了有限元模型并验算了渡槽支座反力,验证了支座设计的合理性;最后,针对支座施工的技术要点进行了探讨。An introduction was made on the scheme comparison and selection,design and checking calculation of the support of a pre-stressed continuous girder-type aqueduct over Nanliujiang River.Firstly,based on the actual conditions of the project,the advantages and disadvantages of three different support schemes were analyzed before the optimal scheme was determined.Subsequently,two software of Midas-civil and Dr.Bridge were used to estab-lish the finite element model and calculate the counterforce of the aqueduct support,which verified the rationality of support design.Finally,the key technical points of support construction were discussed.
