摘要:
为研究不同因素对钢纤维混凝土(SFRC)路面接缝传荷性能衰减规律的影响,进行了20个不同传力杆长度、直径、混凝土板厚度及钢纤维掺量的路面板试件疲劳试验.简单介绍了试验的方案设计,包括原料选择、因素水平选取、试件制作和加载方案确定等.结果表明:掺加钢纤维能够有效提高路面板接缝的传荷性能,降低传荷系数衰减速率;不同因素下的SFRC试件接缝传荷系数衰减曲线特征相似,分为快速衰减和平稳下降两个阶段,当钢纤维体积掺量≤0.6％时曲线表现为三阶段衰退;传力杆直径、长度及钢纤维掺量的增加均能提高接缝传荷性能,但提高幅度十分有限,其中钢纤维掺量影响最大;接缝传荷系数衰退速率随钢纤维掺量的增加而减小,与传力杆直径、长度及混凝土板厚度因素无关;试验条件下,荷裁作用100万次后的SFRC试件传荷系数仍保持在90％以上,具有优良的传荷能力.试验结果为SFRC路面结构设计提供了参考.
Abstract:
In order to study the impact of various parameters on attenuation law of joint load transfer efficiency of steel fiber reinforced concrete (SFRC) pavement,20 pavement specimens with different dowel bar diameter,length,thickness of concrete slab and content of steel fibers were tested in fatigue experiments.The paper briefly introduced the test arrangement including the raw materials of specimens,the parameters and production of specimens,as well as the loading system.It was shown that the steel fiber added in concrete pavement could effectively improve the load transfer efficiency and reduce the attenuation rate of load transfer coefficient.The attenuation curves of joint load transfer coefficient of SFRC specimens under different factors had similar characteristics,which could be divided into two stages:rapid attenuation and steady decline.However,the curve showd three-stage decay when the content of steel fiber was less than or equal to 0.6％.Although the increase of dowel bar diameter,length and content steel fiber could improve the joint loading performance,the increase range was extremely limited,and the impact of steel fiber content was the largest.The decline rate of load transfer coefficient,which had no relations with dowel bar diameter,length and concrete slab thickness,decreased with the increase of steel fiber content.After the load was applied 100 million times in the experiment conditions,the load transfer coefficient of SFRC specimens was remained above 90％,which showed a good load transfer capacity.The test results could provide a reference for SFRC structural design.
