1、摘要隨著人們對大型重要橋朵安全性、耐久性與正常使用功能的日漸關(guān)注，橋梁健康監(jiān)測的研究與監(jiān)測系統(tǒng)的開發(fā)應(yīng)運(yùn)而生。為了保證既有橋的安全運(yùn)營和盡可能處長其安全使用年限，應(yīng)對既有橋進(jìn)行檢測，而且應(yīng)定期進(jìn)行所謂全面檢查就是對橋梁的引道、周邊環(huán)境、地基下部結(jié)構(gòu)、上部結(jié)構(gòu)、橋面(包括橋面鋪裝層、伸縮縫、人行道、欄桿、防撞設(shè)施、排水設(shè)施、照明及防雷設(shè)施)、支座等作全面查看、量測。測設(shè)墩臺中心位置的工作稱為橋梁墩臺定位。這是墩臺施工放樣的基礎(chǔ)。橋梁墩臺定位所依據(jù)的原始資料是橋軸線控制樁的里程和橋梁墩臺的設(shè)計里程。根據(jù)里程可以算出它們之間的距離，并按此距離標(biāo)定出墩臺的中心位置。測設(shè)方法則
2、視河寬、水深及墩位的情況，可采用直接測設(shè)或角度交會的方法。墩、臺中心位置定出以后，還要測設(shè)出墩、臺的縱橫軸線，以固定墩臺方向，本文提出了橋梁定位的研究以及橋梁的檢測方法分析。關(guān)鍵詞：定位分析測量-32-ABSTRACTAsthelargeimportantbridgeandsecurity,durabilityandnormalfunctionisconcerned,thehealthmonitortheresearchanddevelopmentofmonitoringsystemhasemerged.inordertoensurethesafetyoperatio
