The invention relates to the technical field of bridge engineering automatic monitoring data processing, in particular to a structure temperature effect separation method based on a temperature orthogonal space. The method comprises the following steps: expressing daily temperature data of each measuring point in a cubic spline function mode; constructing a temperature orthogonal space based on the cubic spline function of each measuring point; based on the temperature orthogonal space, extracting a temperature effect component in the overall structure response signal; and according to the overall structure response and the temperature effect component, determining the structure response component of the live load effect. The scheme provides a novel rapid standardized separation processing method for realizing the temperature effect component in the overall structure response. 本发明涉及桥梁工程自动化监测数据处理技术领域，具体涉及一种基于温度正交空间的结构温度效应分离方法。该方法包括以下步骤：将每个测点每天温度数据采用三次样条函数方式进行表达；基于各个测点的三次样条函数，构建温度正交空间；基于温度正交空间，提取整体结构响应信号中的温度效应分
