The car dumper shed is an important transportation and transfer hub building in the bulk cargo yard，which is equipped with large dumpers，car pullers and other important equipment. The underground structure is complex with the large load.In order to analyze the key and difficult point of underground structure design of car dumper shed，we combine with the underground structure engineering of dumper in Xuzhou Shundihe operation area，use the general structural finite element method，and systematically analyze the car dumper shed from the aspects of action calculation，action combination，structure modeling，result post-processing，element design，structure anti-floating design and etc.The results show that it is feasible to analyze structure as a whole by finite element analysis software，and some parts of stress concentration need to be reasonably judged before structural design.
