朱伯芳工程师在他的论文“支墩坝温度应力的近似分析中,对支墩和坝面的接触面间,因水温和气温的显著差别引起的应力,提出了一个近似计算的方法。在目前,这还是一个比较切合实用的方法,所惜作者在一系列的比较复杂的推导过程中,产生了一些错误,妨碍了结果的正确性,以后更有一些同志提出了若干修正,但都没有能彻底解决问题。这里愿将我们在数学推演中,发现的一些问题,提出来请大家指正。作者在计算支墩受剪力(?) (1)作用下的变位时,采用应变协调方程
In his paper, “Approximate Analysis of Temperature Stress in a Pier and Dam”, Zhu Bofang’s engineer proposed an approximate calculation method for the stress caused by the significant difference between water temperature and air temperature at the contact surface between the abutment and the dam surface, This is still a more practical method. Those who cherish misunderstandings have made some mistakes in a series of relatively complicated deductions, which have hindered the correctness of the results. Some later, some comrades proposed a number of amendments, but none of them completely Solve the problem here would like to put forward some questions we found in the mathematical deduction, please correct me.The author in calculating the displacement of the pier by shear (?)
