摘　　要：介绍了钢管混凝土的特点及发展前景。通过实验结果分析了钢管混凝土的承载强度性能,在钢管的约束下可以显著地改善混凝土的延性,提高混凝土的承载力和变形能力。The feature and development prospect of steel pipe concrete are introduced. Through experiment result, the bearing strength property of steel pipe concrete is analysed. Under the binding of steel pipe, the ductility of concrete is improved greatly, the bearing and deformation capacity of concrete are raised.
