【摘要】：我國半數(shù)橋梁達(dá)到二十年的使用年限,加之標(biāo)準(zhǔn)荷載的遞增變更,公路等級的提高升級,舊有橋梁的安全性、適用性及耐久性問題日漸凸顯。本文基于橋梁檢測評估和維修加固技術(shù)的理論研究,通過對某鋼筋混凝土T型梁橋進(jìn)行了現(xiàn)場檢測、動靜載試驗(yàn),分析評估該橋技術(shù)狀況,研究橋梁碳纖維筋加固技術(shù),論文主要內(nèi)容有:(1)分析總結(jié)造成橋梁承載力衰減因素和常見病害成因,論述國內(nèi)外橋梁檢測評估及碳纖維材料加固技術(shù)研究和應(yīng)用成果。(2)闡述基于外觀缺陷及內(nèi)部損傷的無損檢測技術(shù)與基于動靜載實(shí)驗(yàn)的結(jié)構(gòu)測試技術(shù),評定某鋼筋混凝土T型梁橋的技術(shù)狀況。(3)探討基于T梁底部受拉區(qū)采用表層內(nèi)嵌9×Φ6碳纖維筋法進(jìn)行補(bǔ)強(qiáng)T型梁橋加固技術(shù),研究在某鋼筋混凝土T型梁橋應(yīng)用碳纖維筋加固技術(shù)方案。(4)在某鋼筋混凝土T型梁橋碳纖維筋加固工程實(shí)踐中,分析和總結(jié)了碳纖維筋加固的施工工藝及技術(shù)要點(diǎn)。
[Abstract]:Our half bridge for twenty years, coupled with the increasing change of standard load, the improvement of road grade upgrade, the old bridge safety, applicability and durability issues have become increasingly prominent. This theory on reinforcement technology of bridge detection and evaluation and maintenance based on the adoption of a reinforced concrete T beam bridge site test, static load test, analysis and evaluation of the technical condition of bridge reinforcement technology of bridge, carbon fiber reinforcement, the main contents of this thesis are: (1) analyze and summarize the causes of common diseases and attenuation factors of bridge bearing capacity, the assessment and carbon fiber reinforcement technology research and application achievements of the domestic and international bridge (2) states. Nondestructive testing technology and technical structure test of static and dynamic load experiment based on the appearance of defects and internal damage based on the technical condition evaluation of a reinforced concrete T beam bridge. (3) to investigate the beam bottom based on T The surface tension zone with 9 x phi 6 carbon fiber reinforcement reinforcement of the reinforced T beam bridge, research on reinforcement in a reinforced concrete T beam bridge using carbon fiber reinforcement technology. (4) in a reinforced concrete T beam bridge carbon fiber reinforcement engineering practice, analyzed and summarized the construction technology and key points of carbon fiber reinforcement.
