style="text-align:left;">     (1) 外部_钢加固法?br />     外部_钢加固法是一U采用化学粘l剂钢板直接粘贴在混凝土构件表?Q让钢板和؜凝土构g形成受力整体 ,从而去提高承蝲力、增大g性、刚度和满正常使用要求的加固方法?br />     (2)预应力加固法?br />     预应力加固法是采用外加预应力的钢拉杆对结构进行加固的Ҏ ,适用于要求提高承载力、刚度和抗裂性及加固后所占用I间的桥梁。可分ؓ预应力拉杆加固和预应力撑杆加?,其中预应力拉杆加Z要用于受弯构?,以梁wؓ锚固?, 通过预应力张拉对梁的受拉区域施加外力 ,以抵消结构本w的自重 ,减少车辆药作用下的应力 , 能够减少梁体出现q多的裂~?,以及减小裂缝宽度。预应力撑杆加固主要用于桥梁下部l构的u心受压墩?,但在实践中桥梁墩柱加Z很少采用q种Ҏ?br />     (3)加大截面加固法加大截面法<br />     也称为外包؜凝土加固法。是用增大؜凝土l构物的截面面积和配{进行加固的一U方法。这U加固方法要求被加固的桥梁下部结构能够承受更多的自重 ,能够提供更高的承载力。通常情况?,以加厚桥面板或加大主梁的梁肋宽度Z?br />     (4)_脓FRP 加固法?br />     _脓FRP加固法是采用高强度或高弹性模量的U维复合材料 ,用专门配|的_脓树脂或浸渍树脂粘贴在桥梁混凝土构件表?nbsp;,使之与原构g形成整体共同受力的加固方法。目?l构工程中常用的FRP材料有玻璃纤l?GFRP) 、碳U维(CFRP)和芳U纤l?AFRP)3U?其中以碳U维增强复合材料(CFRP)应用更多?br /> </p> <p style="text-align:center;"> <br /> </p> <p
