摘　　要：植筋技术目前相关的计算公式和技术规程仍然是建立在单向拉拔试验结果的基础上,单向拉拔试验中植筋的受力不能充分反映实际工程中植筋的真实受力状态。本文设计制作了8根采用植筋技术进行受拉主筋搭接的钢筋混凝土梁,全部试验梁承受静力荷载至破坏。文中给出了相关的试验结果,并按普通钢筋混凝土适筋梁正截面平衡条件进行计算,求出钢筋混凝土植筋受弯构件的极限承载力,并将试验结果与之进行比较。对植筋技术在结构加固和建筑改建中的应用提出了若干建议。Pertinent formulas and technical specifications of chemically bonded anchor are based on prism pullout test and these experimental results can't reflect the true cases for their stress of adhesive reinforcing rods which are different form those in beam.Eight RC.beams with tensile reinforcement bars connected by chemical adhesive were tested under bending load.The paper shows experimental results and compares the difference of the tested result and the calculated one according to cross-section area equilibrium equation of Rc.beam.The result provides the base for further research of chemical adhesive steel bar in concrete structures.
