摘　　要：提出了一种新型的加固改建旧的T型简支梁的方法。其主要特点是 ,在对旧桥主体结构—T梁勿需进行大的改造情况下 ,经采用新材料新工艺 ,仅仅在原桥T梁顶面上可靠地重新浇筑一层钢筋混凝土的桥面铺装 ,作为T梁结构承重的一部分断面 ,并将原简支梁改变为连续结构。A new way for strengthening and rebuilding the T-beam simple supported bridges is presented in this paper. Main properties include: only a bridge deck pavement is needed to be cost on the T-beam top of the old bridge by using the new materials and new technology, which is used as a partial section for T-beam structure bearing. The original simple supported beam shall be changed as the continuous structure, and there is no need for changing the T-beam----the main structure of the old bridge greatly. The authors hope to discuss the new ideas on bridge strengthening according to this practical engineering.
