This paper introduced the main conditions of checking of statically indeterminate structure internal force diagram,taking a symmetrical statically indeterminate frame as an example,analyzed the check problem of symmetry statically indeterminate structure internal force diagram, pointed out to symmetrical structure,if the moment graph was anti-symmetric,chose the units bending moment graph as the positive asymmetry basic structure could not reach the purpose of checking,and vice versa.%介绍了校核超静定结构内力图的主要条件，以某对称超静定刚架为例，分析了对称超静定结构内力图的校核问题，指出对于对称结构，若其弯矩图为反对称，选用单位弯矩图为正对称的基本结构则达不到校核的目的，反之亦然。
