中文摘要：
为深梁的试验、设计和施工提供基本依据，应用改进的稳健设计法，并引入新的信噪比，考虑剪跨比、混凝土强度、水平箍筋屈服强度和竖向箍筋屈服强度等因素．用软化桁架模型分析钢筋混凝土深梁抗剪强度，并应用改进的稳健设计法对影响深梁抗剪强度的因素进行分析，得出了各种影响因素的重要程度．深梁的抗剪强度对混凝土强度这个因素最为敏感，剪跨比次之，水平钢筋屈服强度、竖向钢筋屈服强度影响最小．与田口方法相比改进的稳健设计法的分析结果与试验结果吻合较好，应用更加准确、方便．
英文摘要：
To provide bases for the tests, design and construction of deep beams, the improved robust design method and the new signal-to-noise ratio were employed. Parameters including the shear span ratio, the concrete strength, the yield strength of horizontal hoop, and the yield strength of vertical hoop were taken into account. The shear strength of deep beams and the factors affecting it were analyzed by the softened truss model and the improved robust design method, respectively. The results show that the strength of concrete has the largest influence on the shear strength of component, the next is the shear span ratio, the yield strength of horizontal reinforce and the yield strength of vertical reinforce have the least influence on it. The analysis result of improved robust design method agrees better with the test result compared with Taguchi method, and it is more accurate and more convenient than Taguchi method.
