水利学报在19s8年1、2两期发表了朱伯芳同志的“支墩坝温度应力的近似分析”一文和汪景琦同志等的两篇讨论,现在愿将个人的一些看法,提出来供商讨。一、关于支墩和坝头间相互作用力问题原文假定两者之间仅作用有剪应力,我觉得不只是剪应力存在,而且还有垂直应力存在,因为:(1)原文既将坝头当作单维杆件来考虑,就不应该忽略坝头受弯时所产生的挠度和角转,坝头在这里可以看成悬臂梁,则坝顶部分挠度一定累积成比较大的数字,和高度 Journal of Hydraulic Engineering published two articles by Comrade Zhu Bofang in his article entitled “An Approximate Analysis of the Temperature Stress of Pier Rock Dam” in January and December of 19s8 and Comrade Wang Jingqi. Now it is willing to put forward some personal opinions for discussion. First, on the support pier and the interaction between the dam The original text assumes that there is only a shear stress between the two, I think not only the existence of shear stress, but also the existence of vertical stress, because: (1) As a single-dimensional rod to consider, you should not ignore the deflection and corner rotation when the dam bending, the head can be seen here as a cantilever, then the top part of the deflection must be accumulated into a relatively large number, and height
