A railway overload and unbalanced load detection system and method, comprising steel rails (1). Two sampling points (2) are respectively provided on two sides of a rail web (12) of each steel rail (1) between every two sleepers (3); the sampling points (2) on each side are symmetrically provided with respect to the steel rails (1); an optical fiber sensitive element (4) is obliquely and fixedly provided on each sampling point (2), and the sampling points (2) are provided on neutral axes of the steel rails (1); two optical fiber sensitive elements (4) on the same side of each steel rail (1) are arranged to form an included angle of 90 degrees; the optical fiber sensitive elements (4) are provided on the sampling points (2) on the neutral axes, so that outputs of the optical fiber sensitive elements (4) are shear waveforms when the steel rails deform under force; the two optical fiber sensitive elements (4) on the same side of the steel rail (1) are provided to form the included angle of 90 degrees. During overload and unbalanced load detection, the shear waveforms of the two optical fiber sensitive elements (4) are ensured to be complementary so as to form a collection interval capable of performing collection during a whole detection process, and the precision of detection is ensured. Moreover, the sampling points (2) on each side are symmetrically provided with respect to the steel rails (1), so as to overcome rolling pendulum interference caused by S-shaped operations of trains.
