《建筑技术》1981年第3期刊登了《钢筋混凝土台座计算》一文,为墩式台座的设计提供了有关资料。本文想对原文计算中的有关问题提些看法。 1.稳定计算中的倾复点的选择所谓稳定计算,对于墩式台座而言,即进行抗倾复计算。倾复点的准确选择,要确保使用安全可靠,又要经济。为了便于阐述,用A_(理论)表示理论倾复点、A_(建议)表示建议倾复点、A_(原文)表示《钢筋混凝土台座计算》一文的倾复点位置。按理论计算,倾复点A_(理论)应在混凝土台面的表面处,但考虑到混凝土台面抹面层施工质量,并为 “Architecture Technology” published the article “Calculation of Reinforced Concrete Pedestal” in the 3rd issue of 1981, which provided relevant information for the design of the pier type pedestal. This article would like to give some opinions on the relevant issues in the original calculation. 1. Selection of the plunge point in the stabilization calculation The so-called stability calculation is to perform the anti-rollback calculation for the pier type pedestal. The exact choice of the plunge point must ensure that the use of safety and reliability, but also economic. For ease of explanation, use A_(theory) to represent the theoretical pour point, A_(recommendation) to suggest the pour point, and A_(the original) to indicate the location of the plunge point in the “Calculation of Reinforced Concrete Pedestal” article. According to theoretical calculations, the pour point A_(theoretical) should be at the surface of the concrete deck, but considering the construction quality of the concrete deck, it is
