| 摘 要： | 在对连续配筋混凝土路面(CRCP)病害调查的基础上,选定冲断和密集裂缝作为CRCP性能评价指标,修筑了11个CRCP试验段,通过改变混凝土组成、基层类型、钢筋防护、纵横向钢筋的夹角、纵向钢筋的埋置深度和主动控制裂缝间距等因素,测试了混凝土的抗压强度、抗拉强度、抗弯拉强度、抗压模量和抗弯拉模量;调查了各试验段裂缝发展状况,进行了落锤式弯沉仪(FWD)测试,并对比分析了各因素对CRCP性能的影响。结果表明,混凝土材料、纵横向钢筋的夹角和基层类型对密集裂缝的影响大于混凝土面板和基层之间夹层的影响,1~5 m的主动控制裂缝间距可以有效防止自然裂缝的产生。 |

| Abstract: | Based on the field investigations of CRCP disasters,the cluster cracking and punchout were adopted as the performance criteria.Eleven test sections were designed and constructed to test the compressive strength,tensile strength,flexural strength,compressive modulus and flexural modulus of concrete,through changing the concrete material,base,erosion prevention of steel,the angle between transverse steel and longitudinal steel,the depth of longitudinal reinforcement,and the distance of cracks.The cracks in ea... |
