订阅交jiao通tong量liang增zeng长chang迅xun猛meng，大da件jian运yun输shu车che和he超chao重chong车che日ri益yi增zeng多duo，同tong时shi由you于yu高gao速su公gong路lu设she计ji速su度du高gao，对dui高gao速su公gong路lu桥qiao梁liang的de破po坏huai程cheng度du越yue来lai越yue大da。经jing过guo几ji年nian或huo十shi几ji年nian的de通tong车che运yun营ying，各ge种zhong桥qiao梁liang病bing害hai相xiang继ji出chu现xian，如ru桥qiao面mian铺pu装zhuang混hun凝ning土tu局ju部bu或huo大da面mian积ji破po坏huai，桥qiao面mian产chan生sheng坑keng槽cao；桥qiao面mian伸shen缩suo严yan重chong，产chan生sheng桥qiao头tou跳tiao车che，危wei及ji行xing车che安an全quan；河he床chuang冲chong刷shua严yan重chong，基ji桩zhuang混hun凝ning土tu剥bo落luo、漏lou筋jin等deng，这zhe就jiu需xu要yao桥qiao检jian车che等deng检jian测ce设she备bei对dui桥qiao梁liang维wei护hu保bao养yang工gong作zuo及ji时shi到dao位wei才cai能neng保bao证zheng桥qiao梁liang的de正zheng常chang使shi用yong。
桥qiao梁liang检jian测ce车che实shi际ji上shang是shi一yi种zhong可ke以yi为wei桥qiao梁liang检jian测ce人ren员yuan在zai检jian测ce过guo程cheng中zhong提ti供gong作zuo业ye平ping台tai的de专zhuan用yong汽qi车che。作zuo业ye平ping台tai装zhuang备bei在zai汽qi车che底di盘pan上shang，可ke以yi随sui时shi移yi动dong位wei置zhi， 能neng安an全quan、快kuai速su、高gao效xiao地di让rang作zuo业ye人ren员yuan进jin入ru作zuo业ye位wei置zhi。桥qiao梁liang检jian测ce车che最zui早zao出chu现xian在zai欧ou美mei，用yong于yu桥qiao梁liang流liu动dong检jian测ce或huo维wei修xiu作zuo业ye，技ji术shu含han量liang很hen高gao。 经jing常chang使shi用yong的de桥qiao检jian车che从cong结jie构gou形xing式shi上shang主zhu要yao分fen为wei2种zhong：吊diao篮lan式shi桥qiao梁liang检jian测ce车che和he桁heng架jia式shi桥qiao梁liang检jian测ce车che。
吊diao篮lan式shi桥qiao检jian车che也ye叫jiao臂bi架jia式shi桥qiao检jian车che，其qi结jie构gou小xiao巧qiao，可ke有you线xian、无wu线xian操cao作zuo，灵ling活huo方fang便bian，有you时shi候hou还huan可ke以yi做zuo为wei高gao空kong作zuo业ye车che使shi用yong，价jia格ge相xiang对dui桁heng架jia式shi桥qiao检jian车che低di。一yi般ban是shi采cai用yong一yi级ji伸shen缩suo、二er级ji回hui转zhuan、三san级ji变bian幅fu机ji构gou，形xing成cheng三san维wei空kong间jian、6个ge自zi由you度du的de空kong间jian运yun动dong体ti系xi， 可ke以yi安an全quan、快kuai捷jie地di将jiang工gong作zuo人ren员yuan和he设she备bei送song到dao桥qiao下xia幅fu度du允yuan许xu的de任ren意yi位wei置zhi。
先xian进jin水shui平ping的de桁heng架jia式shi桥qiao梁liang检jian测ce车che结jie构gou比bi较jiao复fu杂duo，价jia值zhi昂ang贵gui；但dan工gong作zuo稳wen定ding，能neng够gou实shi现xian连lian续xu不bu间jian断duan作zuo业ye，所suo提ti供gong的de是shi一yi个ge相xiang对dui较jiao大da的de作zuo业ye面mian，检jian测ce范fan围wei广guang、承cheng载zai能neng力li强qiang、作zuo业ye效xiao率lv高gao。
大da型xing桥qiao检jian车che的de试shi制zhi成cheng功gong，数shu字zi化hua大da桥qiao计ji算suan仿fang真zhen系xi统tong在zai安an徽hui铜tong陵ling长chang江jiang大da桥qiao的de成cheng功gong预yu测ce，桥qiao梁liang模mo态tai测ce试shi技ji术shu、强qiang迫po振zhen动dong时shi桥qiao梁liang振zhen动dong测ce试shi技ji术shu、桥qiao梁liang动dong挠nao度du信xin号hao恢hui复fu技ji术shu等deng的de成cheng功gong运yun用yong，都dou代dai表biao着zhe中zhong国guo公gong路lu桥qiao梁liang检jian测ce技ji术shu有you了le很hen大da的de发fa展zhan。相xiang信xin随sui着zhe计ji算suan机ji技ji术shu和he电dian子zi技ji术shu成cheng果guo等deng在zai桥qiao梁liang检jian测ce当dang中zhong的de使shi用yong，桥qiao梁liang维wei修xiu养yang护hu技ji术shu的de完wan善shan，桥qiao梁liang运yun行xing的de安an全quan会hui得de到dao更geng加jia充chong分fen的de保bao证zheng。
