摘要
分析研究了光纤光栅传感与测试技术在大型土木工程结构监测中的应用;通过在加固后重载吊车梁圆弧端头的应力测试,对光栅传感器在结构测试中的布设、连接和监测等进行了测试与研究,测试结果表明:该测试技术的测试数据稳定、可靠,与理论计算结果吻合较好,是进行结构安全健康监测的有效手段.
The application of testing technology was analyzed and studied in inspecting of civil engineering structure, and the stress of crane beam that has been reinforced using circle member was tested. The disposition, connection and inspection of fiber bragg grating was tested and studied; The results of test indicate that the data were steady and reliable, and the test data were in accord with the theory calculated value. It is valid way in testing of structure healthy monitoring using the fiber bragg grating.
