近年来福建省高速公路建设步伐有所加快,并且在桥梁设计中大量地采用了预应力混凝土准连续梁。该桥型具有简支梁施工方便的优势,它的使用不仅可以降低工程造价,而且能提高工效,大大缩短了建设周期。在营运中,它又具有连续梁的受力特性,行车舒适且养
In recent years, Fujian Province has accelerated the pace of highway construction, and in the bridge design a large number of prestressed concrete quasi-continuous beams. The bridge has the advantages of easy construction of simple beams, its use can not only reduce the cost of the project, but also improve work efficiency, greatly reducing the construction period. In operation, it also has a continuous beam of force characteristics, driving comfortable and support
