多车道高速公路货车车道路面结构内部应变的现场测试与分析

摘要

In order to obtain the internal mechanical response of pavement structure under the role of actual vehicle load, relying on the reconstruction and extension project for Shenyang-Siping Expressway, basing on a large amount of research, test, theoretical analysis and numerical simulation, the truck lane pavement structure type of multilane expressway is put forward, and the monitoring is performed for the mechanical response inside the pavement structure under the role of different actual vehicle loads through laying the strain sensor measuring element in asphalt layer, so as to provide larger reference value for the performance and combinational design of truck lane pavement for multilane expressway.%为了能够获得实际车辆荷载作用下路面结构内部的力学响应,以沈平高速公路改扩建工程为依托,在大量的调研、试验、理论分析、数值模拟的基础上,提出多车道高速公路货车车道路面结构形式,并在沥青层中埋设应变传感器测量元件,对路面结构内部在不同实际车辆荷载作用下的力学响应进行监测,对多车道高速公路货车车道路面的性能和组合设计具有较大的参考价值.
