In　recent　years,　air-supported　membrane　structures　have　been　widely　used　in　China＇s　environmental　protection　of　closed　coal　yards　and　in　sports　stadiums.　There　have　been　breakthroughs　year　by　year　in　the　numbers　constructed,　unit　area,　and　span.　At　present,　the　largest　span　of　an　air-supported　membrane　structure　coal　shed　has　reached　198　m.　As　the　span　increases,　the　force-bearing　performance　of　the　structure　is　more　closely　related　to　its　shape.　In　this　paper,　based　on　a　225mx198mx66m(Length　x　width　x　height)　long-span　air-supported　membrane　structure　test　model,　the　form-finding　and　state-finding　analysis　of　the　air-supported　membrane　structure　with　longitudinal　and　transverse　cable　nets　were　carried　out,　and　the　results　were　compared　with　the　forming　test　results.　The　results　show　that　the　prestressed　state　of　the　structure　obtained　by　the　state-finding　analysis　is　closer　to　the　test　results.　However,　there　is　a　specific　difference　with　the　target　height.　At　the　same　time,　the　form-finding　analysis　can　accurately　find　the　target　height,　but　the　structure＇s　cable　force　and　section　shape　are　quite　different　from　the　test　results.
