Cfrp加固梁在承受彎曲荷載時的破壞是鋼筋屈服后碳纖維斷裂和鋼筋屈服后混凝土壓碎。本文通過應變相容方法和對破壞機理的定義，由給定的cfrp橫截面積預測加固梁的極限彎曲強度；或者相反，在已知加固梁的極限彎曲強度時可以求出所需的cfrp橫截面積。This paper presents an analysis method of mechanical behavior of aged concrete structures on elastic theory, and analyses the main causes of load bearing performance of concrete structures. the paper also illustrates some studies where structures exposed to the marine environment showed early deterioration and analyses the main causes of structural concrete deterioration, including concrete carbonization, corrosion mechanisms of concrete, and mechanisms of steel corrosion due to the penetration of chloride ions into the concrete. it shows that corrosion of the reinforcements is the main cause of structural concrete deterioration
本論文提出老化混凝土板的分層彈性理論，對混凝土結構的承載能力的影響進行分析；對浙江沿海混凝土結構及其構件的抗彎、抗剪、粘結性能以及結構的動力性能進行分析研究；提出了影響沿海混凝土結構耐久性的主要因素一混凝土的碳化作用，堿骨料反應，混凝土的腐蝕機理以及鋼筋混凝土中鋼筋銹蝕的影響因素。The liquid - gas method is improved based on the above methods, overcoming the defects of gbj82 - 85. using the liquid - gas method, permeability condition of concrete can be tested and indicated quickly, efficiently, and the influences on concrete of alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw can be inflected indirectly. it is significant on the research and monitor on the durability of concrete
溶液氣壓法是在上述方法之上進行改進提高的，克服了國標gbj82 - 85方法中的許多不足之處，能夠多角度、快速、高效、真實、準確地再現現場混凝土的滲透情況，並且能間接反映堿-骨料反應、鋼筋銹蝕、碳化、硫酸鹽侵蝕及凍融破壞的影響，對混凝土耐久性的監測與研究具有重要意義。For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。Catalysts were prepared by impregnation reduction, thermal reduction, advanced thermal reduction and sol - gel methods from these metals. electrochemistry measurements, xrd, tem were used to test these catalysts. the results showed that these metals have some electrocatalysis activities towards hydrogen oxidation reaction
