摘　　要：论述了用支撑柱加固无梁板的选点原则。屈服线理论能量法用于无梁板加固分析的“抗力单元”理论、及该理论应用于加固分析的可行性。“抗力单元”理论同时也是一种无梁板抗力分析的新方法。分别给出了采用１点、５点加固支撑形式的弯曲抗力计算公式及公式的适用条件。通过一常用无梁板算例的加固分析得到了抗力提高的一般规律。The principle for choosing supporting points for strengthening flat - slab was discussed. The energy law of yield line theory was applied to the theory of 'resistance unit' of flat slab strengthening analysis. The theory of 'resistance unit' was used in feasibility of strengthening analysis and it is also a new method to analyze the resistance of flat - slab. Bending capacities calculating formulas of one point, five points strengthening support type were put forword, and applying condition of the formulas was also given. A general rule of raising resistance by strengthening analysis of a flat - slab was verified by a calculation example.
