摘　　要：某地下结构施工完成后因地面以上需增加结构,改变了原有结构的受力。受地下空间的使用功能制约,上部结构框架柱不能全部落入地下室基础内,需经顶板梁转换,因此需对顶板梁进行加固设计。通过分析工程特点,选用增大截面法进行转换梁的加固设计,结果表明,该方法具有良好效果。A basement structure is changed for a new store is added over it. Some flame columns of up structure cannot extend into the basement which will change the internal layout of the original basement. The up beams of the original basement are needed to support the columns of the new added structure. In this paper, the enlarging section method is used to strengthen the up beams and the results suggest the method is applicable and reliable.
