摘要:
针对车辙产生的外部影响因素(温度、荷载),在对典型路面结构温度场分析以及材料特性试验的基础上,采用合理的车辙计算模型和考虑连续变温的模拟分析方法,利用ABAQUS模拟分析了不同温度场、不同接地压力下车辙的变化规律.结果表明:通过路面温度场的引入和定义材料参数随温度场变化,利用连续变温的路面车辙模拟分析方法可以更加符合实际的进行车辙模拟分析; 车辙主要产生于平均气温高于20℃的高温季节的高温时段; 在温度条件和累积作用时间相同的情况下,车辙量随接地压力的增大而增加,且基本成线性增长关系,而实际车辆超载时,路面车辙将呈非线性显著增大.
Abstract:
Based on temperature field analysis and laboratory material tests of pavement, a reasonable simulation model and method considering consecutively variable temperature is developed to study the effect of exterior factors(temperature and load)on rutting of pavement and analyze the behavior of rutting under different temperature and loading by ABAQUS. The results show that, the rutting analysis close to the field condition can be simulated using the simulation method considering consecutive temperature variation; rutting usually occurs at the average daily air temperature of 20 ℃ or higher, and the higher the average daily air temperature, the longer the time with the potential of rutting occurrence; under same temperature and accumulated loading time, rutting depth increases roughly linearly with the increasing contact pressure, while the increase will have more chance to be nonlinear on condition of overloading.
