In　order　to　establish　accurate　compressive　constitutive　model　of　Hybrid　Fiber-Reinforced　Concrete　(HFRC),　10　groups　of　HFRC　specimens　containing　polyvinyl　alcohol　(PVA),　polypropylene　(PP),　and　steel　fibers　are　designed　and　compressive　testing　is　conducted.　On　the　basis　of　summarizing　and　comparing　the　existing　research,　accuracy　of　various　stress-strain　constitutive　model　is　compared　and　the　method　of　calculating　fitting　parameters　is　put　forward,　peak　stress,　peak　strain,　and　elastic　modulus　of　specimens　with　different　fiber　proportion　are　analyzed,　the　calculation　expressions　of　each　fitting　parameter　are　given.　The　results　show　that,　under　the　condition　that　the　volume　of　the　hybrid　fiber　is　2%　with　the　proportion　of　the　steel　fiber　increase,　the　strength　of　the　specimen　increases,　the　peak　strain　decreases　slightly,　and　the　elastic　modulus　increases　significantly.　In　specimens　mixed　with　PVA-PP　hybrid　fiber,　with　the　increase　of　PVA　fiber　proportion,　the　peak　stress　and　elastic　modulus　of　the　material　are　improved,　and　the　peak　strain　are　decreased.　The　existing　stress-strain　expressions　agree　well　with　the　tests.　Accuracy　of　exponential　model　proposed　in　this　paper　is　the　highest,　which　can　be　applied　in　engineering　and　nonlinear　finite　element　analysis　of　components.
