Abstract:It has the advantages of rapid construction and less traffic disturbance during the construction to conduct frame culvert construction using the open-cut multi-directional prefabricated assembly technology combined with large-size frame structure. Taking the underpass tunnel project of Shugang Road in Xiamen, the operational safety and durability of the structure were considered, and the frame culvert structure was analyzed by ANSYS software combined with the large-scale scaled model test. The most suitable embedding depth was determined as 1-3m. And according to the influence of changes in various sizes of the structure, the crosssectional size of the structure was optimized.
Keywords:frame culvert; partial prefabricated assembly; finite element analysis; most suitable embedding depth; optimization design
