摘　　要：利用均匀设计方法设计试验方案,进行了不同偏心率、不同长细比的钢管煤矸石砼偏心受压构件的试验研究,指出了均匀设计的优越性;推导出了计算钢管煤矸石砼偏心受压构件承载力的经验公式;分析了长细比与偏心距对偏心受压构件承载力的交互影响;推导出了极限状态时偏心受压构件中截面的中性轴、挠度与偏心距和长细比之间的关系式。Uniform design method is used to design the test plan. Tests of columns with different steel ratio and slenderness ratio under bias compression are carried out. The advantage of the uniform design is pointed out. The experience formula to calculate the ultimate bearing capacity is obtained. The relation formular of neutral axle and deflection changing with steel ratio and slenderness ratio in ultimate state are put forward.
