| Abstract: | A great progress has been made in the construction technology of the long-span prestressed concrete continuous rigid-frame bridge in China. However, a variety of diseases have been discovered in some old bridges. Based upon the summarization of the main types of the diseases in this kind of bridge, the significance function of monitoring is discussed during the process of its reinforcement construction. Exampled by the reinforcement of external prestressed method, the main points and the matters needing atten- tion are expounded during its monitoring process. |
