將混凝土管片應平穩安放于HRJ抗彎試驗機→≥20mm橡膠墊放于加載點→1/3管片跨度加載點→抗彎荷載分配梁→分級加載，每級恒載時間≥5min→記錄每級荷載值作用下的各測點位移→混凝土管片出現裂縫後持續荷載10min→混凝土管片開裂荷載實測值→加載至設計荷載持續荷載30min，記錄最大裂縫寬度，卸載。加載達到設計荷載並持荷30min後，沒有觀察到裂縫或裂縫寬度不大于0.2mm,應判定該檢驗批管片抗彎性能符合設計要求。在混凝土管片的抗彎性能檢驗過程中，管片若出現的裂縫較多，無法逐條記錄時，可選擇若幹條具有代表性的主要裂縫進行記錄。例如，首次出現的裂縫、長度和寬度比較大的裂縫等。管片厚度300mm350mm500mm600mm650mm；管片寬度1m1.2m1.5m1.8m2m；500kN纖維混凝土管片抗彎曲試驗機；500kN鋼管片抗彎曲試驗機；管片內徑3m5.4m5.5m12m13.7m；500kN複合管片抗彎曲試驗機；1000kN鐵路隧道鋼筋混凝土襯砌管片抗彎曲性能試驗機；GB/T22082-2017預制混凝土襯砌管片；TB/T3353-2014鐵路隧道鋼筋混凝土管片；CJJ/T164-2011盾構隧道管片質量檢測技術標准；JC/T2030-2010襯砌管片生産工藝技術規程；JGJ/T385-2015高性能混凝土評價標准；JGJ/T294-2013；JC/T2351-2016；GB/T50081-2019；DL/T5150-2017；TB 10425-2019；TB 10424-2018；TB 10402-2019；TB 10064-2019；TB/T3275-2018；TB 10077-2019；TB 10218-2019；GB/T31061-2014；GB/T50344；ASTM C496；ASTM C1106；jnshiyanji.com；ASTM C902；ASTM C936；EN 1338；ISO 4108；JIS R1535；三缸全自動鋼筋彎曲試驗機；全自動鋼筋正反向彎曲試驗機；雙缸聯動鋼筋反向彎曲試驗機；603金屬材料管塑性變形彎管試驗機；GB/T244-2020金屬材料管彎曲試驗方法；65mm專用彎管試驗機；鋼板鋼帶180°彎曲試驗機；500kN1000kN2000kN電液伺服材料彎曲試驗機；3000kN微機控制鋼軌靜彎曲試驗機；混凝土管片抗滲漏檢測裝置；500kN混凝土管片抗拔力試驗裝置；1000kN玻璃彎曲強度試驗機；汽車防撞鋼梁板彎曲強度試驗機；6mm10mm13mm金屬線材反複彎曲試驗機；井蓋壓力疲勞試驗裂紋裂縫測量試驗機；1000kN200kN井蓋壓力疲勞一體化試驗機；電液伺服井蓋壓力疲勞試驗機系統；井蓋井箅承載能力動靜測試系統；雨水儲水模塊變形抗壓強度蠕變應力試驗機；1000kN電液伺服井蓋壓力試驗機；2000kN大空間多功能井蓋壓力試驗機；1250kN電液伺服井蓋壓力試驗機；英國標准協會BSI歐洲標准化委員會CEN標准制定修訂進行實驗論證；1000kN井蓋傾斜試驗機；MWF120kN井蓋拔出力試驗機；100kN塑料檢查井荷載試驗機；2000kN移動式混凝土壓力試驗機；3000kN混凝土伺服壓力強度試驗機；5000kN全自動混凝土快速壓力試驗機；低溫環境混凝土抗壓強度熱膨脹系數試驗機；低溫環境混凝土抗拉強度試驗機；低溫環境混凝土拉伸沖擊試驗機；混凝土砌塊磚抗壓強度試驗機；全級配混凝土抗壓強度試驗機；600kN混凝土路緣石抗折抗壓試驗機；10MN混凝土構件多功能試驗機系統；2000T橡膠支座壓剪試驗機；鋼絞線鋼材雙位拉伸試驗機；鋼絞線偏斜拉伸試驗機；多工位金屬材料拉伸應力松弛試驗機；1000h金屬材料拉伸應力松弛試驗機；300kN鋼絞線鋼筋鋼棒應力松弛試驗機；鋼絲鋼絞線鋼筋鋼棒高溫應力松弛試驗機；鋼絲鋼絞線鋼筋鋼棒應力腐蝕松弛試驗機；650T微機控制靜載錨固試驗機；鋼絞線錨具夾具組裝件錨板強度靜載承壓試驗機；500N～300kN高溫拉伸蠕變持久強度試驗機；單軸拉伸蠕變應力斷裂試驗機；電子式蠕變持久強度試驗機；電池包組機械強度三工位蠕變試驗機；礦用錨杆錨索鋼絞線靜載抗拔拉伸綜合試驗機；無振動下拉上壓伺服液壓萬能材料試驗機；3000kN無振動伺服萬能材料試驗機；1000kN無振動鋼筋機械連接拉伸試驗機；5000kN礦用高強度圓環鏈機械性能試驗機；4000kN礦用扁平接鏈環機械性能試驗機；2000kN鋼筋套筒灌漿連接件反複拉壓試驗機；灌漿套筒力學性能試驗機；SWLT-5全自動鋼筋重量長度測試儀；
