《城市高架桥养护技术规程(DB3302\T1083-2017)/宁波市地方标准规范》:
  7.1.1 上部结构包括主梁、横梁、横向联系等。
  7.1.2 在高架桥上通行的车辆,应符合限载要求,不允许超重车辆通行。超重车辆通行后,应及时进行检查,必要时应进行检测。
  7.1.3 上部结构养护可按宁波市《城市桥梁养护技术规程》规定的相关要求执行,并符合7.2~7.4的要求。
  7.2预应力混凝土梁
  7.2.1 预应力混凝土梁应每年进行一次结构裂缝和表面温度裂缝观测。结构裂缝应重点检查受拉、受剪区域,表面温度裂缝应重点检查构件的较大面。
  7.2.2 预应力混凝土梁构件裂缝宽度在允许值内(≤0. 2mm),应对裂缝进行封闭处理;当裂缝宽度大于允许值时,应对梁构件进一步检查以确定处理方案。
  7.2.3 预应力混凝土构件受压区一旦发现裂缝,应立即封闭交通,严禁车辆桥上、下通行,并委托相应资质的检测部门进行梁构件可靠性评估,判别裂缝的危害程度,提出相应的处理措施;预应力混凝土构件受拉区出现结构性裂缝,应进行裂缝危害性评估,确定处理措施。
  7.2.4 预应力混凝土梁构件发生混凝土剥落、露筋等现象时,应及时清除钢筋锈迹,凿去表面松动的混凝土后进行修补。对损坏面积较大的结构,凿除混凝土后不得明显降低结构的承载力,必要时宜采用分批修补。
  7.2.5 当预应力混凝土梁封锚端混凝土出现裂缝、剥落、渗漏、穿孔,预应力锚具暴露时,应及时对预应力锚具刷防锈漆,重做封锚端混凝土。
  7.2.6 预应力混凝土梁构件出现明显损伤或产生明显变形、移位时,应根据检测评估结果进行设计和修复。
  7.2.7 预应力混凝土主梁挠度超过规定允许值时,应进行结构评估,并提出加固措施。
  7.2.8 预应力混凝土梁加固可采用下列方法:
  a)横向联系损伤导致各构件不能共同受力时,应对横向联系进行修复、加固,必要时进行桥面补强;
  b)梁的刚度、强度、稳定性及抗裂性不足时,可采用加大结构断面尺寸或增加钢筋数量等方法进行加固,加大断面及增加配筋数量应根据计算确定;
  c)采用体外预应力补强加固。
