摘　　要：用预应力混凝土材料修建的各类桥梁在我国现役的桥梁中占绝大多数。由于各种原因,预应力混凝土材料修建的桥梁在使用多年后,或多或少都会出现一些病害,特别是近几年,地区交通流量增大以及车辆超重等现象的增多导致桥梁出现较多的病害,这大大缩短了桥梁的寿命。因此,对产生病害的桥梁进行必要的维修将对延长桥梁寿命起到非常重要的作用。根据某一大桥的病害情况,对大桥的主要病害情况及成因进行分析,然后根据病害的情况制定了详细的维修方案,对维修过程进行了比较详细的叙述,对施工工艺进行了比较详细的介绍,并对施工过程中需要注意的事项进行了详细的阐述。Many bridges with prestressed concrete materials accounted for the vast majority of the existing bridge in our country.A variety of reasons,prestressed concrete bridge built in use for many years,more or less some diseases,especially in recent years,led to an increase of the regional traffic flow increases and overloading bridges appear more disease,which greatly shortens the life of the bridge.Therefore,the necessary repairs to produce disease bridge extended bridge will play a very important role in life.According to the situation of the disease of a bridge,the Bridge,the main diseases and causes analysis to develop a detailed maintenance program,and then according to the situation of the disease,a more detailed description of the repair process,a more detailed description of the construction process and the need to pay attention to in the construction process elaborated.
