摘要
预应力混凝土连续刚构桥具有跨度比较大,施工技术比较成熟的特点,普遍采用悬臂浇筑法或悬臂拼装法进行施工。在我们采用悬臂施工时,要考虑很多的因素去保障工程的质量和安全,其中因为混凝土材料内部的温度效应严重时所导致的结构出现明显裂缝的情况,需要引起足够的关注。
Prestressed concrete continuous rigid frame bridge has the characteristics of large span and mature construction technology.Cantilever casting method or cantilever assembling method are widely used in construction.When it use cantilever construction,it need to consider many factors to ensure the quality and safety of the project.Among them,the obvious cracks in the structure caused by the serious temperature effect inside the concrete material need to be paid enough attention.
