The invention discloses a real-time monitoring system for bridge pier deformation caused by shield construction, which comprises a shield tunnel, a concrete bearing platform, a bridge pier, a bridge pier, an L-shaped corner brace fixer and a three-axis acceleration sensor, the three-axis acceleration sensor is used for collecting corner data of the bridge pier and uploading the corner data to the remote intelligent end cloud platform through wireless signals. The invention further discloses a real-time monitoring method for bridge pier deformation caused by shield construction. The method comprises the following steps that S4, the displacement of the bridge pier in the direction perpendicular to the shield tunnel is delta Y = h * sin delta theta X; and S5, the vertical displacement delta Z of the bridge pier is equal to (h-h * cos delta theta X) + (h-h * cos delta theta Y). According to the rotation angle variable quantity of the three-axis acceleration sensor at the moment t, the inclination angle change val
