锥型钢管混凝土基础及运用分析

Tapered Concrete-Filled Steel Tube Foundation and Its Application Analysis

在钢管和混凝土共同作用下,构件承载力水平得到提升,钢管结构保护了混凝土,避免发生变形,使整体结构的强度更高。论文阐述了钢管混凝土的特点及锥形钢管混凝土的特点,对锥形钢管混凝土基础构件压扭试验进行探讨,并具体分析锥形钢管混凝土基础在冻土区域杆塔施工中的应用情况。

Under the joint action of steel tube and concrete,the bearing capacity of structure is improved,and the steel tube structure protects the concrete,avoids deformation,and has higher overall strength.In this paper,the characteristics of concrete-filled steel tubes and tapered concrete-filled steel tubes are described,the compression-torsion test of tapered concrete-filled steel tubes foundation components is discussed,and the application of tapered concrete-filled steel tubes foundation in tower construction in permafrost region is analyzed in detail.
