Method for evaluating spatial and temporal distribution of rebound modulus of roadbed in cold region
The invention discloses a cold region roadbed resilience modulus spatial and temporal distribution assessment method, and belongs to the field of road assessment. According to the method, the spatial and temporal distribution of the rebound modulus of the roadbed can be accurately evaluated according to the environmental information (roadbed temperature and humidity) in the roadbed structure. Especially in a cold region, the roadbed is subjected to frost heaving and thaw collapse along with seasonal changes, and the roadbed structure is gradually degraded due to freeze-thaw circulation, so that the rebound modulus of the roadbed is reduced. According to the method, the spatial and temporal distribution of the rebound modulus of the roadbed in the cold region is evaluated, and the behaviors of the roadbed material in different seasons and under different environmental conditions can be predicted, so that a more stable and durable pavement structure can be designed. According to the invention, rapid and continuous monitoring of the rebound modulus of the roadbed can be realized, the data collection efficiency is greatly improved, and the workload is reduced. And meanwhile, the change of the roadbed performance can be found in time through real-time monitoring, so that the possibility is provided for timely maintenance and maintenance, the maintenance cost is reduced, and the service life of the roadbed is prolonged.
一种寒区路基回弹模量时空分布评估方法，属于道路评估领域。本发明可根据路基结构内环境信息(路基温、湿度)，准确地对路基回弹模量的时空分布进行评估。尤其是在寒区，路基会随着季节变化出现冻胀融沉，冻融循环会导致路基结构逐渐劣化，从而降低其回弹模量。通过该方法对寒区路基回弹模量时空分布进行评估，可以预测路基材料在不同季节和不同环境条件下的行为，这有助于设计更为稳定和耐久的路面结构。本发明可实现对路基回弹模量的快速、连续监测，大幅度提高数据收集的效率和减少工作量。同时，实时监测使得能够及时发现路基性能的变化，为及时维修和养护提供了可能，减少了维护成本和延长了路基使用寿命。
