分离式立交桥预应力混凝土T梁后张拉施工技术研究

Separate Type Overpast Prestressed Concrete T-beam Post-tension Construction Techniques Research

后张法是先浇筑水泥混凝土,待达到设计强度的75%以上后再张拉预应力钢材以形成预应力混凝土构件的施工方法。结合106国道分离式立交桥30 m混凝土T梁施工,对后张法施工关键技术进行探讨。

It was priority lay cement concrete,treat run up to design strength 75% upwards aback anew stretching prestress steel products withal form prestressed concrete member job practice that post-tensioning method. Text incorporation 106 national highway separate type overpast 30m concrete T-beam construction practice, make an approach to post tensioning method construction critical technology.
