摘　　要：依据钢筋混凝土受弯构件的极限承载弯矩不小于相同条件下素混凝土的开裂弯矩的原则导出了倒锥形独立基础底板的最小配筋率值，并且确定了其的计算截面，为设计钢筋混凝土倒锥形独立基础提供了依据。The minimum steel ratio in inverted taper shaped isolated spread footings under individual column is studied, according to the principle of which the flecure strength of RC beams is not less than the cracking moment of plain concrete beam under the same conditions. The result can be applied to the design of RC inverted taper shaped isolated spread footings.

关 键 词：钢筋混凝土 素混凝土 倒锥形独立基础 最小配筋率
