中文摘要：

为了给沥青路面结构响应监测找到科学有效的测 试手段,本文进行了沥青路面响应光纤Bragg光栅（FBG）实时监测 的研究。应用单轴压缩试验对采用的FBG传感器进行标定,得到了标定方程。基于提 出的沥青路面 FBG传感器埋设方法,在沥青路面成功埋设了FBG传感器。将静载监测结果与BISAR 3.0程序 计算结果进 行了比较。对不同轴重、不同汽车行驶速度及不同温度条件下的沥青路面结构动力响应进行 了实时监测。结果 表明,提出的沥青路面FBG传感器埋设方案可使传感器的成活率达到87%；静载实测结果与 计算结果较为接近,FBG监测结果有效且能准确反映沥青路面各工况下的应变时程；当车速 降低8km/h时,路面应变响应降低达100με以上；而路面温度增 长8℃,路面的竖向变形增长了近200με。

英文摘要：

In order to find a scientific and effective test method for asphalt pa vement response monitoring,the fiber Bragg grating （FBG） sensor used to measure asphalt pavement response is studied .The FBG sensor used in this paper is calibrated by uniaxial compression test,by which the calibration equ ation is obtained.FBG sensors are embeded in asphalt pavement successfully based on embedded technology provi ded in this paper.Results measured under static load and results calculated by BISAR 3.0are compared.St ructure responses of asphalt pavement under different loads,velocities and temperatures are measured.Resul ts show that the FBG sensors embedded scheme proposed in this paper can ensure that sensors′ survival rate r eaches 87%.Strain values measured by FBG sensors are close to calculated results by BISAR 3.0,which indic a tes that the response monitored by FBG sensor can effectively and accurately reflect the strain time history under different pavement conditions.When the speed is reduced by 8km/h,pavement strai n response is reduced by more than 100με.Moreover,when temperature is increased by 8℃, pavement strain response is increased by more than 200με.
