500kN铁路隧道盾构衬砌预制混凝土管片抗弯曲试验机，对预制混凝土衬砌管片施加抗弯设计荷载，检测管片在抗弯荷载作用下的变形、检测管片表面裂缝的产生和变化，评价管片的抗弯曲性能。测定混凝土管片抗弯荷载、管片挠度、管片水平位移、管片分级加载、管片恒载时间、管片裂缝开裂荷载实测值、管片最大裂缝宽度、管片破坏荷载测试。
 将混凝土管片应平稳安放于HRJ抗弯试验机→≥20mm橡胶垫放于加载点→1/3管片跨度加载点→抗弯荷载分配梁→分级加载，每级恒载时间≥5min→记录每级荷载值作用下的各测点位移→混凝土管片出现裂缝后持续荷载10min→混凝土管片开裂荷载实测值→加载至设计荷载持续荷载30min，记录最大裂缝宽度，卸载。加载达到设计荷载并持荷30min后，没有观察到裂缝或裂缝宽度不大于0.2mm,应判定该检验批管片抗弯性能符合设计要求。在混凝土管片的抗弯性能检验过程中，管片若出现的裂缝较多，无法逐条记录时，可选择若干条具有代表性的主要裂缝进行记录。例如，首次出现的裂缝、长度和宽度比较大的裂缝等。管片厚度300mm350mm500mm600mm650mm；管片宽度1m1.2m1.5m1.8m2m；500kN纤维混凝土管片抗弯曲试验机；500kN钢管片抗弯曲试验机；管片内径3m5.4m5.5m12m13.7m；500kN复合管片抗弯曲试验机；1000kN铁路隧道钢筋混凝土衬砌管片抗弯曲性能试验机；GB/T22082-2017预制混凝土衬砌管片；TB/T3353-2014铁路隧道钢筋混凝土管片；CJJ/T164-2011盾构隧道管片质量检测技术标准；JC/T2030-2010衬砌管片生产工艺技术规程；JGJ/T385-2015高性能混凝土评价标准；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；三缸全自动钢筋弯曲试验机；全自动钢筋正反向弯曲试验机；双缸联动钢筋反向弯曲试验机；603金属材料管塑性变形弯管试验机；GB/T244-2020金属材料管弯曲试验方法；65mm专用弯管试验机；钢板钢带180°弯曲试验机；500kN1000kN2000kN电液伺服材料弯曲试验机；3000kN微机控制钢轨静弯曲试验机；混凝土管片抗渗漏检测装置；500kN混凝土管片抗拔力试验装置；1000kN玻璃弯曲强度试验机；汽车防撞钢梁板弯曲强度试验机；6mm10mm13mm金属线材反复弯曲试验机；井盖压力疲劳试验裂纹裂缝测量试验机；1000kN200kN井盖压力疲劳一体化试验机；电液伺服井盖压力疲劳试验机系统；井盖井箅承载能力动静测试系统；雨水储水模块变形抗压强度蠕变应力试验机；1000kN电液伺服井盖压力试验机；2000kN大空间多功能井盖压力试验机；1250kN电液伺服井盖压力试验机；英国标准协会BSI欧洲标准化委员会CEN标准制定修订进行实验论证；1000kN井盖倾斜试验机；MWF120kN井盖拔出力试验机；100kN塑料检查井荷载试验机；2000kN移动式混凝土压力试验机；3000kN混凝土伺服压力强度试验机；5000kN全自动混凝土快速压力试验机；低温环境混凝土抗压强度热膨胀系数试验机；低温环境混凝土抗拉强度试验机；低温环境混凝土拉伸冲击试验机；混凝土砌块砖抗压强度试验机；全级配混凝土抗压强度试验机；600kN混凝土路缘石抗折抗压试验机；10MN混凝土构件多功能试验机系统；2000T橡胶支座压剪试验机；钢绞线钢材双位拉伸试验机；钢绞线偏斜拉伸试验机；多工位金属材料拉伸应力松弛试验机；1000h金属材料拉伸应力松弛试验机；300kN钢绞线钢筋钢棒应力松弛试验机；钢丝钢绞线钢筋钢棒高温应力松弛试验机；钢丝钢绞线钢筋钢棒应力腐蚀松弛试验机；650T微机控制静载锚固试验机；钢绞线锚具夹具组装件锚板强度静载承压试验机；500N～300kN高温拉伸蠕变持久强度试验机；单轴拉伸蠕变应力断裂试验机；电子式蠕变持久强度试验机；电池包组机械强度三工位蠕变试验机；矿用锚杆锚索钢绞线静载抗拔拉伸综合试验机；无振动下拉上压伺服液压万能材料试验机；3000kN无振动伺服万能材料试验机；1000kN无振动钢筋机械连接拉伸试验机；5000kN矿用高强度圆环链机械性能试验机；4000kN矿用扁平接链环机械性能试验机；2000kN钢筋套筒灌浆连接件反复拉压试验机；灌浆套筒力学性能试验机；SWLT-5全自动钢筋重量长度测试仪；
