本文首先指出了现行计算公式(包兴格公式和捷尔万纳巴巴公式)的缺点和不准确性,然后根据混凝土的套箍“强化”理论用极限平衡法导得计算混凝土和配筋混凝土局部承压极限强度及抗裂强度的新公式,井用国内外的试验资料对其准确性进行了校核,获得了令人满意的结果。 This article first pointed out the shortcomings and inaccuracies of the current calculation formulas (Bushinger’s formula and the Tyrwana Baba’s formula), and then used the limit equilibrium method to derive concrete and reinforcement according to the concrete hoop “strengthened” theory. The new formula for the ultimate strength and cracking strength of local concrete under pressure, and the accuracy of the well with domestic and foreign test data were checked and satisfactory results were obtained.
