摘　　要：实验研究了膨胀剂掺量和钢管厚度对不同强度等级方钢管膨胀混凝土力学性能的影响.研究结果表明:在一定膨胀剂掺量条件下,方钢管膨胀混凝土极限承载力比方钢管普通混凝土提高了15%;钢管厚度越大,方钢管膨胀混凝土极限承载力越大.The effect of the content of expansive additive and steel tube wall thickness on the mechanical properties of expansive concrete filled square steel tube were studied. The experimental results show that the limit loading capacity of expansive concrete filled square steel tube is increased by 15% more than that of common concrete filled square steel tube by adding some content of expansive additive. The greater the steel tube wall thickness, the higher the limit loading capacity of expansive concrete filled square steel tube is.
