Double-bridge static cone penetration probe and static cone penetration test method based on FBG
The invention discloses a double-bridge static cone penetration probe and a static cone penetration test method based on FBG. The probe adopts double bridge structure. The double-bridge static cone penetration probe based on FBG broadens the technical means of static cone penetration test. The pressure sensing beam structure introduced in this invention can automatically offset the temperature term in subsequent data processing to realize temperature self-compensation. The structure has the advantages of high sensitivity, good stability, insulation, waterproof, corrosion resistance, and easy to realize long-distance signal transmission and measurement control. The structure can work in harsh environments, laying a foundation for the subsequent application of FBG static cone penetration technology to actual projects.
本发明公开一种基于FBG的双桥静力触探探头及静力触探试验方法，采用双桥结构，基于FBG的双桥静力触探探头，拓宽了静力触探试验的技术手段。本次发明引入的压力感测梁结构，在后续数据处理中能将温度项自动抵消，实现温度自补偿，具有灵敏度高、稳定性好、绝缘、防水、耐腐蚀，容易实现远距离信号传输和测量控制等优点，并且可在恶劣环境下工作，为后续将FBG静力触探技术广泛应用于实际工程奠定基础。
