摘要
基于光时域反射原理（OTDR）的路面裂缝传感技术,通过自制裂缝调制器测量了沥青混凝土中裂缝宽度与光功率损耗的关系,并提出了Logistic和Gomperz预测模型,对2种预测模型在1.5~2.5mm宽的裂缝的重点关注区域内的识别度D和误差率进行对比分析,得出结论：三参数Logistic预测模型对于裂缝宽度的预测效果更好。
The distributed sensing technology for pavement cracks was put forward based on optical time-domain reflectometer（OTDR）.The relationship between the width of the cracks of asphalt concrete and optical power loss was measured by a homemade crack modulator,and the Logistic and Gomperz prediction models were proposed.The prediction models were compared on the recognition degree and error rate of the critical area of 1.5-1.5 mm cracks.The results indicate that the Logistic model with three parameters make better predictions.
