摘要
文章结合烟威高速公路大修工程实例,对比分析了被动裂缝控制和主动裂缝控制对连续配筋混凝土路面(简称CRCP)病害的影响,建议采用主动裂缝控制技术以延长路面使用寿命。同时,通过ABAQUS有限元软件模拟CRCP真实路面情况,力学计算结果表明:小裂缝间距不利于混凝土板和钢筋的受力,降低了路面使用性能。
Combined with Yanwei expressway repair project,the article analysed the influences of passive and active crack control on CRCP diseases and recommended the active crack control technology to prolong pavement service life. Real road conditions were also simulated by the nonlinear finite element software ＂ABAQUS＂. Results shown that the small crack spacing was hammful for stress of concrete and steel and reduced pavement performance.
