摘要
介绍了 3 2m后张法超低高度预应力混凝土曲线梁概况 ,为提高高强混凝土抗应变能力和抗裂能力 ,提出在混凝土中掺加适量钢纤维及矿物外加剂DBF的方法 ,从而提高了 3 2m超低高度梁制造技术的可靠性。
The general features of 32 m post tensioned prestressed shallow concrete girder are introduced. In order to improve its strain capacity and breaking strength the construction method that using steel fiber and mineral DBF as admixtures is proposed in order to ensure the reliability of fabrication techniques of this shallow girder.
