Abstract	本发明涉及工程力学领域，公开了一种测量结构双向应变梯度场的方法、传感器及应用，其中，传感器包括柔性基体，以及嵌设在柔性基体内的相互垂直的两组光纤对；每组光纤包括若干光纤对；组内的光纤对相互平行，光纤对包含一对相互平行的第一光纤和第二光纤，光纤对所在平面与两组光纤对所成平面相互垂直；在测量构件的应变梯度时，柔性基体贴合在构件上，且光纤对所在平面垂直于构件的中性层。本发明利用分布式光纤传感技术，可以提高应变数据的测量能力，降低应变数据的测量成本。
Other Abstract	The invention relates to the field of engineering mechanics, and discloses a method for measuring a bidirectional strain gradient field of a structure, a sensor and application. The sensor comprises aflexible substrate and two groups of optical fiber pairs which are embedded in the flexible substrate and are perpendicular to each other; each group of optical fibers comprises a plurality of optical fiber pairs; the optical fiber pairs in the group are parallel to each other and comprise a first optical fiber and a second optical fiber which are parallel to each other, and the plane where the optical fiber pairs are located is perpendicular to the plane formed by the two optical fiber pairs; when the strain gradient of the component is measured, the flexible substrate is attached to the component, and the plane where the optical fiber pair is located is perpendicular to the neutral layer of the component. The distributed optical fiber sensing technology is utilized, the measuring capacity of strain data can be improved, and the measuring cost of the strain data is reduced.
