The invention discloses a beam deformation real-time measurement method under a pre-deformation condition. The method comprises the following steps: acquiring an initial form of a measured beam; setting a sensor measuring point along the beam axis direction to obtain a strain value in the beam axis direction; and calculating the deformation deflection of the beam according to the obtained strain value, and superposing the deformation deflection with an initial state on the basis of a calculation result to obtain a real deformation value of the beam. According to the invention, real-time measurement of beam deformation under the pre-deformation condition is realized. 本发明公开了一种预变形条件下梁变形实时测量方法，包括以下步骤：获取被测梁的初始形态；沿梁轴线方向设置传感器测量点，以获取梁轴线方向的应变值；根据得到的应变值，计算梁的变形挠度，在计算结果的基础上与初始状态叠加，得到梁的真实变形值。本发明实现在预变形条件下对梁变形实时测量。
