【Abstract】 New development of the slab deflection measurement for high concrete faced rock-fill dam is presented in this paper.The technology of three dimensional Fiber Optic Gyro(FOG) system is proposed and applied to measure the slab deflection of the Si-anjiang concrete faced rock-fill dam,and remarkable results are achieved.The FOG is developed in small dynamic state and in high accuracy;its operating pipe and the measuring vehicle are reasonable in design,and the testing values are steady,reliable,and good at repeatability.更多还原
