| 摘 要： | 本文用白光散斑法测量箱式桥模型采光孔附近的应变场。模型表面用闪光铝粉进行斑化,以此克服用玻璃微珠或用银粉进行斑化所带来的缺点。以逐点法提取位移信息,用电子计算机对位移场进行处理求得应变场,从而克服模型整体位移对测量结果的影响。

| Abstract: | The strain field around the lighting window of the box-formed bridgemodel is measured with the white light speckle method. The surface of thebridge model is coated with aluminium powder instead of micro glass beadsor silver powder to avoid some defects. The displacement information isobtained point by point and the strain field is depicted from the displacementfield with the help of computer, thus she effect of the displacement of thebridge model as a whole on the results of the measurement can be eliminated. |
