摘要:
采用四点抗弯实验评估不同力学性能的修补材料与基体水泥沥青砂浆的匹配性；采用有限元模型分析了不同弹性模量差异的修补材料与基体砂浆组合试块的应力应变分布.结果表明,修补材料与基体砂浆之间弹性模量的差异决定着组合试块的荷载传输效率与破坏形式,是影响两者力学性能匹配性的主要因素.针对水泥乳化沥青砂浆的受力形式,采用四点弯曲疲劳试验对两者的匹配性实验结果做了进一步的验证.
Abstract:
The compatibility of mechanical properties betweencement and asphalt mortar and repair materials wasstudied by the fbur point bending method．With the help of finite element model，the eH．ect of difkrence in modulus of substrate mortar and repair mortar on the stress and strain distribution of composite sample was studied．Resultsindicated that difference in modulusof substrate monarandrepair mortardecided the loading transfer efficiency and failure mode，which mainly innuenced compatibility of mechanical properties．Accord．ing to the serVice state of CAM，fourpoint bending fatigue test wasemployed to identify the compatibility be．tweenCAMand repair mate“a1．
