摘要
后张法预应力混凝土空心板梁是预应力混凝土简支梁桥和先简支后连续桥中常用的结构形式之一,它具有自重轻、抗震抗裂性能好、稳定性高、梁高较低、预制架设方便等特点。随着我国高等级建筑建设的不断发展,预制预应力混凝土桥梁日益显示出广阔的应用前景。
Post-tensioned prestressed concrete hollow slab is the common structure form in supported prestressed concrete girder bridge and the simply supported continuous bridge, it has the characteristics of light weight, seismic crack resistance, high stability, low beam height, convenient pre-set. As the constant development of high-grade building construction, preeast prestressed concrete bridge increasingly shows application prospects.
