将振弦式应变计和半导体类温度传感器用于破损水泥混凝土路面加铺沥青混凝土路面的力学性能监测研究,并在试验路段的实际工程中进了传感器的埋设,结合试验路段路面结构进了有限元力学分析,将理论分析结果同测试结果进行对比分析,验证监测系统有效性,经过一年多的监测,证明了监测系统在破损水泥混凝土路面加铺沥青混凝土路面的力学性能监测的可行性。通过研究为复合路面各结构层的应力和应变状况以及温度场进行长期监测提供一种新的方法,为研究路面材料的力学性能随时间的变异性,深入认识路面使用性能劣化的基本规律提供了技术支持。
Vibrating wire strain gages and semiconductor temperature sensors are used to monitor the mechanical properties of asphalt pavement paved with damaged concrete pavement and embedded in the sensor in the practical engineering of the test section. Through the mechanics analysis, the theoretical analysis results are compared with the test results to verify the effectiveness of the monitoring system. After more than one year of monitoring, the feasibility of monitoring the mechanical properties of the asphalt pavement pavement on the damaged cement concrete pavement is proved. This paper provides a new method for long-term monitoring of stress and strain of various structural layers of composite pavement and temperature field. In order to study the variability of mechanical properties of pavement materials over time, it is provided to understand the basic rules of deterioration of pavement performance Technical Support.
