Abstract
A distributed sensing fiber acoustic emission apparatus and method for monitoring a hydraulic engineering safety behavior includes a fiber-carrying laying module and a fiber acoustic emission module. The fiber-carrying laying module includes an inner supporter, mesh modules and fiber-carrying modules, the inner supporter, the mesh modules and the fiber-carrying modules form a cylindrical shape. The cross section of the inner supporter is in a quadrangle inner-concave shape with the four edges concaved, the four surfaces of the inner supporter are concaved, the mesh modules having a plurality of meshes are respectively disposed in the four concave surfaces of the inner supporter, and the fiber-carrying module is arranged between every two adjacent mesh modules.
