  1. 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。
  2. Through the bonding tests and the theory analysis between the advanced composite glass sheets and the concrete under the general load - carrying condition, the iterative load - carrying condition, the freeze - thaw action, and the defective bonding, the calculative model has been established, and the numerical value of fibre sheet strain under different load - carrying has been confirmed. the bond strength calculative expressions for the concrete bonded with glass fibre sheet under the pull - shear and the bend load - carrying conditions have been established. the author put forward the decreasing coefficient and the calculative expressions for the influence of reinforce effect by the non - effective area and the calculative expressions for the influence of the freeze - thaw action on the carrying capacity of the concrete beams

    本文採用美國泰扶高強復合玻璃纖維布以及與之性能相當、由南京玻璃纖維研究院自行研製開發的egfw430型玻璃纖維布兩種材料，通過在靜載、重復荷載、凍融及有缺陷粘結條件下的高強玻璃纖維布與混凝土粘結性能的試驗研究與理論分析，建立了玻璃纖維布-混凝土的粘結計算模型，明確了不同受力狀態下纖維布應變的設計取值，提出了玻璃纖維布-混凝土抗剪粘結強度的計算公式;確定了考慮非有效粘貼面積對加固效果影響的折減系數;給出了凍融循環次數引起承載力下降的插值計算方法;並驗證了重復荷載作用下玻璃纖維布與混凝土良好的粘結性能。
  3. These problems that the influence of bond behavior among frp layers caused by the freeze - thaw action, and bond behavior between frp and concrete experienced freeze - thaw - iii - action are studied by test. in addition, the influence on integral structures by freeze - thaw action and wet - thermal condition is considered. 6

    對于凍融循環對多層纖維增強復合材料之間粘結性能的影響、 frp片材與受到凍害混凝土的粘結性能問題、凍融循環對frp片材加固混凝土結構整體性能影響問題和濕熱環境對frp片材與混凝土粘結性能的影響問題進行了試驗研究。
