摘　　要：论了自应力钢管混凝土的实验研究，及普通钢管混凝土的缺陷．分析了混凝土自应力钢管混凝土的不足之处，并提出了一种新型式的自应力钢管混凝土──钢管自应力钢管混弟土．实验结果表示：钢管自应力钢管混凝土既实现了相对永久性的自应力，又弥补了混凝土自应力钢管混凝土的不足，为一种比较理想的自应力钢管混凝土实现型式．The experimental study on self-stressing concrete filled steel tubes is made and the defects of common concrete filled steel tubes are presented. Also the disadvantages of self-stressing concrete filled steel tubes induced by concrete are studied and analyzed. A new type of self-stressing concrete filled steel tubes, the self-stressing concrete filled steel tubes induced by steel tube is proposed. The results of the experiment show that self-stressing concrete filled steel tubed induced by steel tube not only achieve the relative permanent self-strexx but also avoid the disadvantages of self-stressing concrete filled steel tubes induced by concrete. Therefore, it is a fairly reasonable type of self-stressing concrete filled steel tubes.
